- the proteins themselves do not have intrinsic catalytic activity, rather they function via association with other proteins to transduce cellular signals.
- a functional TNFR superfamily protein can also exist in a soluble form. Soluble versions ofthe superfamily bind cognate ligands and influence bioavailability. For instance, the osteoprotegerin protein family exists as a soluble protein. (Simonet et al. (1997) Cell 89:309-319.) Many soluble forms of the TNFR have been identified. Certain soluble TNFRs are elevated in disease states such as lupus and rheumatoid arthritis. (Gabay et al. (1997) J. Rheumatol.

- Chromosome Mapping Once the sequence (or a portion ofthe sequence) of a gene has been isolated, this sequence can be used to map the location ofthe gene on a chromosome. This process is called chromosome mapping. Accordingly, portions or fragments ofthe STRIFEl or STRIFE2 nucleotide sequences, described herein, can be used to map the location ofthe STRIFEl or STRIFE2 genes on a chromosome. The mapping ofthe STRIFEl or STRIFE2 sequences to chromosomes is an important first step in correlating these sequences with genes associated with disease.
- STRIFEl or STRIFE2 genes can be mapped to chromosomes by preparing PCR primers (preferably 15-25 bp in length) from the STRIFEl or STRIFE2 nucleotide sequences. Computer analysis ofthe STRIFEl or STRIFE2 sequences can be used to predict primers that do not span more than one exon in the genomic DNA, thus complicating the amplification process. These primers can then be used for PCR screening of somatic cell hybrids containing individual human chromosomes. Only those hybrids containing the human gene corresponding to the STRIFEl or STRIFE2 sequences will yield an amplified fragment. Somatic cell hybrids are prepared by fusing somatic cells from different mammals (e.g., human and mouse cells).
- PCR mapping of somatic cell hybrids is a rapid procedure for assigning a particular sequence to a particular chromosome. Three or more sequences can be assigned per day using a single thermal cycler. Using the STRIFEl or STRIFE2 nucleotide sequences to design oligonucleotide primers, sublocalization can be achieved with panels of fragments from specific chromosomes.

- Fluorescence in situ hybridization (FISH) of a DNA sequence to a metaphase chromosomal spread can further be used to provide a precise chromosomal location in one step.
- Chromosome spreads can be made using cells whose division has been blocked in metaphase by a chemical such as colcemid that disrupts the mitotic spindle.
- the chromosomes can be treated briefly with trypsin, and then stained with Giemsa. A pattern of light and dark bands develops on each chromosome, so that the chromosomes can be identified individually.
- the FISH technique can be used with a DNA sequence as short as 500 or 600 bases.
- clones larger than 1,000 bases have a higher likelihood of binding to a unique chromosomal location with sufficient signal intensity for simple detection.
- Reagents for chromosome mapping can be used individually to mark a single chromosome or a single site on that chromosome, or panels of reagents can be used for marking multiple sites and/or multiple chromosomes. Reagents corresponding to noncoding regions ofthe genes actually are preferred for mapping pu ⁇ oses. Coding sequences are more likely to be conserved within gene families, thus increasing the chance of cross hybridizations during chromosomal mapping.

- an individual's genomic DNA is digested with one or more restriction enzymes, and probed on a Southern blot to yield unique bands for identification. This method does not suffer from the current limitations of "Dog Tags" which can be lost, switched, or stolen, making positive identification difficult.

- the STRIFEl or STRIFE2 nucleotide sequences described herein can be used to prepare two PCR primers from the 5' and 3' ends ofthe sequences. These primers can then be used to amplify an individual's DNA and subsequently sequence it. Panels of corresponding DNA sequences from individuals, prepared in this manner, can provide unique individual identifications, as each individual will have a unique set of such DNA sequences due to allelic differences.
- the sequences ofthe present invention can be used to obtain such identification sequences from individuals and from tissue.
- the STRIFEl or STRIFE2 nucleotide sequences ofthe invention uniquely represent portions ofthe human genome. Allelic variation occurs to some degree in the coding regions of these sequences, and to a greater degree in the noncoding regions. It is estimated that allelic variation between individual humans occurs with a frequency of about once per each 500 bases.
- Each ofthe sequences described herein can, to some degree, be used as a standard against which DNA from an individual can be compared for identification pu ⁇ oses. Because greater numbers of polymo ⁇ hisms occur in the noncoding regions, fewer sequences are necessary to differentiate individuals.
- the noncoding sequences of SEQ ID NOT or SEQ ID NO:5 can comfortably provide positive individual identification with a panel of perhaps 10 to 1 ,000 primers which each yield a noncoding amplified sequence of 100 bases. If predicted coding sequences, such as those in SEQ ID NO: 3 or SEQ ID NO: 7 are used, a more appropriate number of primers for positive individual identification would be 500-2,000. - 58 -

- PCR technology can be used to amplify DNA sequences taken from very small biological samples such as tissues, e.g., hair or skin, or body fluids, e.g., blood, saliva, or semen found at a crime scene. The amplified sequence can then be compared to a standard, thereby allowing identification ofthe origin ofthe biological sample.
- sequences ofthe present invention can be used to provide polynucleotide reagents, e.g., PCR primers, targeted to specific loci in the human genome, which can enhance the reliability of DNA-based forensic identifications by, for example, providing another "identification marker" (i.e. another DNA sequence that is unique to a particular individual).
- an "identification marker” i.e. another DNA sequence that is unique to a particular individual.
- actual base sequence information can be used for identification as an accurate alternative to patterns formed by restriction enzyme generated fragments.
- Sequences targeted to noncoding regions of SEQ ID NOsT or SEQ ID NO: 5 are particularly appropriate for this use as greater numbers of polymo ⁇ hisms occur in the noncoding regions, making it easier to differentiate individuals using this technique.
- polynucleotide reagents include the
- STRIFEl or STRIFE2 nucleotide sequences or portions thereof e.g., fragments derived from the noncoding regions of SEQ ID NO: 1 or SEQ ID NO:5, having a length of at least 20 bases, preferably at least 30 bases.

This can be very useful in cases where a forensic pathologist is presented with a tissue of unknown origin. Panels of s ⁇ ch STRIFEl or STRIFE2 probes can be used to identify tissue by species and/or by organ type. In a similar fashion, these reagents, e.g., STRIFEl or STRIFE2 primers or probes can be used to screen tissue culture for contamination (i.e. screen for the presence of a mixture of different types of cells in a culture). - 59 -

This step is followed by a second hybridization array that allows the characterization of specific mutations by using smaller, specialized probe arrays complementary to all variants or mutations detected. Each mutation array is composed of parallel probe sets, one complementary to the wildtype gene and the other complementary to the mutant gene. - 64 -

- either DNA/DNA or RNA/DNA duplexes can be treated with hydroxylamine or osmium tetroxide and with piperidine in order to digest mismatched regions. After digestion ofthe mismatched regions, the resulting material is then separated by size on denaturing polyacrylamide gels to determine the site of mutation. See, for example, Cotton et al.

- Pharmacogenomics deals with clinically significant hereditary variations in the response to drugs due to altered drug disposition and abnormal action in affected persons. See e.g., Eichelbaum, M., Clin Exp Pharmacol Physiol, 1996, 23(10-11) :983- 985 and Linder, M.W., Clin Chem, 1997, 43(2):254-266.

- G6PD glucose-6-phosphate dehydrogenase deficiency
- oxidant drags anti-malarials, sulfonamides, analgesics, nitrofurans
- a genome-wide association relies primarily on a high-resolution map ofthe human genome consisting of already known gene-related markers (e.g., a "bi- allelic" gene marker map which consists of 60,000-100,000 polymo ⁇ hic or variable sites on the human genome, each of which has two variants).
- Such a high-resolution genetic map can be compared to a map ofthe genome of each of a statistically significant number of patients taking part in a Phase II/III drug trial to identify markers associated with a particular observed drug response or side effect.
- a high resolution map can be generated from a combination of some ten-million known single nucleotide polymo ⁇ hisms (SNPs) in the human genome.

- a method termed the "candidate gene approach” can be utilized to identify genes that predict drag response.
- a gene that encodes a drag target e.g., a STRIFEl or STRIFE2 protein or a STRIFEl receptor ofthe present invention
- all common variants of that gene can be identified in the population and a particular drag response can be associated with one or more genes.
- the activity of drug metabolizing enzymes is a major determinant of both the intensity and duration of drag action.
- the gene coding for CYP2D6 is highly polymo ⁇ hic and several mutations have been identified in PM, which all lead to the absence of functional CYP2D6. Poor metabolizers of CYP2D6 and CYP2C19 quite frequently experience exaggerated drug response and side effects when they receive standard doses. If a metabolite is the active therapeutic moiety, PM show no therapeutic response, as demonstrated for the analgesic effect of codeine mediated by its C YP2D6-formed metabolite mo ⁇ hine. The other extreme are the so called ultra-rapid metabolizers who do not respond to standard doses. Recently, the molecular basis of ultra-rapid metabolism has been identified to be due to CYP2D6 gene amplification.
