Description
本发明是得到美国政府的支持,由美国卫生与人类事业局的国立卫生研究所(NIH)提供资助。基金号为:R01GM55147-01。因此,美国政府在此发明中拥有特定权利。
背景
在本申请全文中,各种出版物引证了其作者和年代,其全部引文是按字母顺序列于本申请专利说明书的结尾,紧靠在所列的序列和权利要求之前。这些文献的全部内容引入本申请,以便于更全面地叙述在本文所述的发明完成时普通技术人员已知的现有技术。
Fas(AP0-1/CD95)和它的配体被认为是凋亡(apoptosis)中重要的信号中介体(Itoh,et al.1991),Fas(Apo-1/CD95)的结构组织形式提示它是肿瘤坏死因子受体超家族中的一个成员,该超家族还包括p75神经生长因子受体(NGFR)(Johnson,et al.1986),T-细胞-活性标记CD27(Camerini,et al..1991),何杰金-淋巴瘤-相关抗原CD30(Smith,et al.1993),人类B细胞抗原CD40(Stamenkovic,etal..1989),T细胞抗原OX40(Mallett,et al.1990).Fas以及它的配体的遗传突变均与小鼠的淋巴组织增殖失调和自身免疫失调有关(Watanabe-Fukunaga,et al.1992;Takahashi,et al.1994)。而且,当T-细胞感染人类免疫缺陷病毒(HIV)时,Fas表达水平改变被认为是诱导凋亡(Westendorp,et al.1995)。用酵母双杂交和生化方法已鉴定出几种Fas-相互作用的信号传导分子,如Fas-结合的磷酸酶-1(FAP-1)(图1)(Sato,et al.1995),FADD/MORT1/CAP-1/CAP-2(Chinnaiyan,et al.1995;Boldin,etal.1995;Kischkel,et al.1995)和RIP(Stanger,et al.1995)。除了FAP-1以外,所有分子都与Fas功能性细胞死亡区域有关,当细胞转染了这些蛋白质时,还与FADD/MORT1或RIP过量表达诱导凋亡有关。相反,FAP-1是唯一的与Fas的负调控区(C-端15氨基酸)有关(Ito,et al.1993),并且抑制Fas-诱导的凋亡的蛋白质。
FAP-1(PTPN13)有几种替换的剪接形式与PTP-BAS/hPTP1E/PTPL1一致(Maekawa,et al.1994;Banville,et al.1994;Saras,etal.1994)。并含有一个膜结合区,它与在细胞骨架相关蛋白,ezrin(Gould et al.1989),radixin(Funayama et al.1991),moesin(Lankes,et al.1991),II型神经纤维瘤基因产物(NFII)(Rouleau,et al.1993),和4.1蛋白(Conboy,et al.1991),以及在PTP酶PTPH1(Yang,et al.1991),PTP-MEG(Gu,et al.1991),和PTPD1(Vogel,et al.1993)中发现的相似。FAP-1包括了令人感兴趣6个GLGF(PDZ/DHR)重复,被认为在蛋白区域中介导分子内和分子间的相互作用。FAP-1的第三个GLGF重复首先被确认为与Fas受体的C-端具有特异的相互作用区域(Sato,et al.1995).提示了GLGF区在将这些蛋白定位于亚膜细胞骨架和/或调节生化活性上起着重要作用。GLGF重复最初是在鸟苷酸激酶和大鼠的后突触密度蛋白中(PSD-95)(Cho,et al.1992)发现的,与果蝇肿瘤抑制蛋白,Letha1-(1)-disc-large-1〔dlg-1〕同源,(Woods,et al.1991;Kitamura,etal.1994)。这些重复可以介导同源和异源二聚化,此二聚化能强烈地影响PTP酶的活性、影响与Fas结合、和/或FAP-1同其他信号传导蛋白的相互作用。最近,报道了这些蛋白的不同PDZ区域与离子通道和其他蛋白C-端的相互作用(图1)(表1)(Kornau,et al.1995;Kim,etal.1995:Matsumine,et al.1996)。

为了便于了解以下的实验材料,常规的方法和/或专业术语,请参阅Sambrook,et al.1989。
本发明提供了一种肽化合物,它能够抑制一种信号-传导蛋白和含有(G/S/A/E)-L-G-(F/I/L)氨基酸序列的胞浆蛋白间的特异结合,其中,每个″-″代表一个肽键,每个括号内包括可相互替换的氨基酸,括号内每个斜线分开的氨基酸是可以替换的。此外,该胞浆蛋白可以含(K/R/Q)-Xn-(G/S/A/E)-L-G-(F/I/L)氨基酸序列,其中,″X″代表任何一种氨基酸,该氨基酸是从一组包含20种天然存在的氨基酸中选择出来的,″n″代表大于等于2小于等于4。特别是,在一优选实施方案中,该胞浆蛋白含SLGI的氨基酸序列。
(K/R/Q)-Xn-(G/S/A/E)-L-G-(F/I/L)氨基酸序列在现有技术中也被称作“GLGF(PDZ/DHR)氨基酸区域”。如本申请中所用的“GLGF(PDZ/DHR)氨基酸区域”意思是指(K/R/Q)-Xn-(G/S/A/E)-L-G-(F/I/L)氨基酸序列。
在一优选实施方案中,该信号-传导蛋白在羧基端有(S/T)-X-(V/I/L)氨基酸序列,其中,每个″-″代表一个肽键,每个括号内包括可相互替换的氨基酸,括号里的每一个斜线分开的氨基酸是可以相互替换的。其中,″X″代表任何一种氨基酸,该氨基酸是从一组包含20种天然存在的氨基酸中选择出来的。
本发明的组合物可以是,不仅限于,抗体,无机化合物,有机化合物,肽,模拟肽化合物,多肽或蛋白,共有一些或全部特性的片段或衍生物,如,融合蛋白。该组合物可以是天然存在的并通过纯化得到,或非天然存在通过合成得到的。
特别是,该肽化合物可以是含有(S/T)-X-(V/I/L)-COOH序列的肽,其中,每个″-″代表一个肽键,每个括号内包括可相互替换的氨基酸,括号里的每一个斜线分开的氨基酸是可以替换的。″X″代表任何一种氨基酸,该氨基酸是从一组包含20种天然存在的氨基酸中选择出来的。在一优选实施方案中,该肽包括下列序列之一:DSENSNFRNEIQSLV,RNEIQSLV,NEIQSLV,EIQSLV,IQSLV,QSLV,SLV,IPPDSEDGNEEQSLV,DSEMYNFRSQLASVV,IDLASEFLFLSNSFL,PPTCSQANSGRISTL,SDSNMNMNELSEV,QNFRTYIVSFV,RETIESTV,RGFISSLV,TIQSVI,ESLV。更优选的实施方案是一种有机化合物,它含有Ac-SLV-COOH序列,其中,Ac代表一个乙酰基,每个“-″代表一个肽键。
下文中提供了本发明的一个例子。乙酰化肽可以在改进的ChemTechACT357仪器上,按以前发表的程序以类推的方法自动合成。每个循环用Wang树脂,所有的氨基酸用Nα-Fmoc保护,然后是20%六氢吡啶/DMF,偶联是用DIC/HOBt,随后用HBTU/DIEA完成。最后的氨基酸偶联上后,在树脂上延伸的肽用Ac2O/DMF乙酰化。用HPLC纯化乙酰化的肽,通过FAB-MS和1H-NMR鉴定其特征。
而且,本领域普通技术人员通晓上述与非-乙酰基,例如,氨基,偶联的合成肽的构建方法。
本发明也提供了一种肽化合物,它能抑制羧基端带有(S/T)-X-(V/I/L)氨基酸序列的信号-传导蛋白和一种胞浆蛋白间特异结合,其中,每个″-″代表一个肽键,每个括号内包括可相互替换的氨基酸,括号内的每个斜线将可相互替代的氨基酸分开,″X″代表任何一种氨基酸,该氨基酸是从一组包含20种天然存在的氨基酸中选择出来的。
本发明的组合物包括抗体,无机化合物,有机化合物,肽,模拟肽化合物,多肽或蛋白,共有一些或全部特性的片段或衍生物,例如,融合蛋白。
本发明也提供一种鉴定一种化合物的方法,该化合物能抑制一种信号-传导蛋白和含有(G/S/A/E)-L-G-(F/I/L)氨基酸序列的胞浆蛋白间的特异结合,其中,每个″-″代表一个肽键,每个括号内包括可相互替换的氨基酸,括号里的每个斜线分开的氨基酸是可以替换的。该方法包括:(a)在允许一种已知的化合物,该化合物曾经显示能替换结合了胞浆蛋白的信号-传导蛋白,和被结合胞浆蛋白形成复合物的条件下,将已结合了信号-传导蛋白的胞浆蛋白与各种化合物接触;和(b)检测步骤(a)中被替换的信号-传导蛋白或形成的复合物,其中,替换作用表示这种化合物能抑制信号-传导蛋白和胞浆蛋白之间的特异结合。
抑制信号-传导蛋白和胞浆蛋白之间的特异结合可以影响报告基因的转录活性。
此外,在步骤(b)中,通过比较在步骤(a)中连接化合物前后报告基因的转录活性来鉴定替换的胞浆蛋白或复合物。这种活性的改变表明信号-传导蛋白和胞浆蛋白间特异结合受抑制以及信号-传导蛋白被替换。
正如本文中所用的“报告基因的转录活性”表示当信号-传导蛋白和胞浆蛋白结合时,报告基因的表达可在观察到的水平上改变。人们也可以通过检测基于信号-传导蛋白和胞浆蛋白之间结合的其他生物功能来鉴定这种化合物。报告基因的例子很多而且技术上是众所周知,包括但不仅限于,组氨酸抗性基因,氨苄青霉素抗性基因,β-半乳糖苷酶基因。
另外,胞浆蛋白是可以结合在固相支持物上。这种化合物也可以结合在固相支持物上并包括一种抗体,一种无机化合物,一种有机化合物,一种肽,一种模拟肽化合物,一种多肽或蛋白。
下面提供一个方法的例子。人们可以用直接鉴定的方法去确认一种化合物,该化合物能抑制信号-传导蛋白和胞浆蛋白之间的特异结合,如该胞浆蛋白与结合了一种可检测标记的化合物之间的免疫-沉淀。此外,可以使用非直接检测方法,该方法检测基因表达水平的提高或减少。正如下面所讨论的,人们能构建融合到LexA DNA结合区的合成肽。这些构建物被转化到L40-细胞株的带有报告基因的适当细胞系中。然后可以通过检测报告基因的表达水平检测抑制是否发生。为了检测报告基因的表达水平,技术上熟练的人能应用各种熟知的方法,例如,用酵母、哺乳类或其他细胞中的双杂交系统。

第一部分实验
实验的详细操作
材料和方法
1.筛选半随机和随机肽基因文库
为了在限制性的DNA序列中产生许多突变,根据文献(Hill等,1987)所叙述的程序,用简并寡核苷酸引起突变的PCR方法,基于人与大鼠之间的同源性,设计两种回文序列,用于构建半随机的基因文库。所用的两个引物是
5’-CGGAATTCNNNNNNNNNAACAGCNNNNNNNNNAATGAANNNCAAAGTCTGNNNTGAGGATCCTCA-3’(Seq.I.D.No.:30)和
5’-CGGAATTCGACTCAGAANNNNNNAACTTCAGANNNNNNATCNNNNNNNNNGTCTGAGGATCCTCA-3’(Seq.I.D.:31)
简述如下,经过HPLC纯化的这两种引物(每种200pmol)在70℃退火,5分钟,于23℃冷却60分钟,然后在Klenow DNA聚合酶作用下(5u),于23℃,60分钟,.用4种核苷酸混合物补平,(每种核苷酸最终浓度为1mM)。加入1μl 0.5M EDTA终止反应。乙醇沉淀来纯化DNA.将得到的双链DNA用EcoRI和BamHI酶切。然后在非变性聚丙烯酰胺凝胶电泳中进一步纯化然后将双链寡核苷酸与pBTM116质粒在EcoRI-BamHI位点进行连接。将连接混合物电转移到E.Coli XL1-Blue MRF’(Stratagene)菌中以构建质粒基因文库。按以前报道的方法进行大批量转化。质粒基因文库转化到L40细胞中(MATa,trp1,1eu2,his3,ade2,LYS2;(1eAop)4-HIS3,URA3::(LexAop)8-LacZ)。该细胞株携带有含有FAP-1 cDNA的PVP16-31质粒(Sato等,1995).将在组氨酸-缺陷的培养基中(His+)形成的克隆转移到含有40μg/ml x-gal的平板上,以测定在平板滤膜实验所产生的兰色反应产物(β-gal+)。对所筛选的His+和β-gal+克隆进行检测以用于进一步分析。有回文结构的寡核苷酸5’-CGGAATTC-(NNH)4-15-TGAGGATCCTCA-3’(seq.I.D.No:32)用于构建随机的肽基因文库。
2.肽的合成
肽的合成是在新型Chemtech ACT357自动合成仪按照以前发表的类似的操作程序自动合成(Schnorrenberg和Gerhardt,1989)。每次循环用Wang树脂(用量为0.2-0.3mmole),所有氨基酸用Nα-Fmoc进行保护。再用20%六氢吡啶/DMF处理去除保护,用DIC/HOBt然后用HBTU/DIEA进行偶联。当最后一个氨基酸被偶联上之后,用Ac2O/DMF对树脂上延长的肽进行乙酰化。最后用TFA处理共同去除所有的保护基团将该肽从树脂上分离下来。乙酰化的肽经过HPLC纯化后,通过FAB-MS和1H-NMR鉴定其特征。
3.利用Fas C端15个氨基酸对Fas/FAP-1结合进行抑制作用的检测
亚克隆到Bluescript pSK-II载体上的HFAP-10 cDNA的体外翻译是利用体外转录/翻译系统(Promega TNT lysate)和T7RNA聚合酶在35S-L-甲硫氨酸存在下,从内部的甲硫氨酸密码子开始翻译,得到的35S-标记蛋白与GST-Fas融合蛋白于4℃共同孵育16小时,该GST-Fas融合蛋白在含150mM NaCl,50mM Tris(pH 8.0),5mM DTT,2mM EDTA,0.1%NP-40,1mM PMSF,50μg/ml亮抑素,1mM联苯胺和7μg/ml抑肽素的缓冲液中,固定在GST-Sepharose 4B亲和层析珠上(Pharmacia),用同样的缓冲液彻底洗4次,通过离心回收带有谷胱甘肽-Sepharose珠的结合蛋白,在煮沸的Laemmili缓冲液中洗脱下来,然后通过SDS-PAGE和荧光学的方法进行分析。

5.结合FAP-1的Fas C端3个氨基酸在体外和在酵母中的相互作用。
构建诱饵质粒pBTM116(LexA)-SLV,-PLV,-SLY/,和SLA并转化到带有pVP16-FAP-1或ras的L40菌株中,从每种转化体中挑出6个单独的克隆,在组氨酸-缺陷的培养基中分析其生长情况。用GST-Sepharose4B亲和层析珠(Pharmacia)纯化GST-Fas,-SLV和PLV。体外结合的方法如上所述。
6.天然的Fas与GST-FAP-1的免疫沉淀反应和Fas/FAP-1与Ac-SLV结合的抑制作用
有FAP-和没有FAP-1的GST-融合蛋白与表达Fas的Jurkat T细胞的细胞提取物共同孵育。利用抗-Fas单克隆抗体进行Western杂交分析以检测结合的Fas(F22120,Transduction Lab)。AC-SLV和AC-SLY三肽用于Fas/FAP-1结合抑制作用的检测。
7.显微注射Ac-SLV到DLD-1细胞株。将DLD-1人肠癌细胞在含10%胎牛血清的RPMI1640培养基中培养。微注射时,在35mm的塑料培养皿上,以1×105细胞/2ml的密度,将细胞接种在CELLoate(Eppendorf)上,生长一天。恰好在进行微注射之前,加入500ng/ml的Fas单克隆抗体CH11(MBLinternational)。所有微注射实验均用自动微注射系统操作(Eppendorf transjector 5246 micro-manipalator5171 和Femtotips)(pantel,等,1995)。合成的三肽以100mM的浓度悬浮在0.1%(W/V)FITC-硫酸葡聚糖(Sigma)/K-PBS中。将样品微注射到DLD-1细胞浆内。注射16-20小时后,用PBS洗细胞,然后用PBS配制的10μg/ml Hoechst33342染细胞。37℃孵育30分钟后,对这些细胞进行照相,计数染色质浓缩的细胞作为凋亡的细胞
8微注射的DLD-1细胞中凋亡的定量分析
每次实验,微注射25-100个细胞。微注射后细胞的凋亡的检测是利用相差以及荧光显微镜对形态学改变进行评价(Wang等,1995)(McGahon,等1995)。数据分析是统计2-3次单独测定的平均值+/-标准误。
讨论
为了签定FAP-1结合所必须的Fas受体C端区域的最小肽,我们利用一系列合成的肽和酵母双杂交系统肽的基因文库(图24),在体外检测Fas/FAP-1结合的抑制作用。首先构建了15种氨基酸融合到LexA DNA结合区域的半随机基因文库(基于人与大鼠之间Fas的同源性)(图2B和2C),然后与起初作为FAP-1分离的pVP16-31(Sato,等,1995)共同转化到L40酵母菌中。从5.0×106转化体中(Johnson等1986)筛选出200His+克隆后,挑出100个β-半乳糖苷酶阳性的克隆用于进一步分析。编码C端15个氨基酸的文库质粒的序列分析揭示了所有的C端氨基酸或是缬氨酸,亮氨酸或是异亮氨酸残基。第二,构建了4-15个氨基酸与LexADNA结合区域相融合的随机基因文库,然后按图2D的策略进行筛选。令人惊奇的是所有C端的第三个氨基酸都是丝氨酸,而且C端氨基酸分析结果与半随机cDNA文库筛选的结果是一致的。在筛选这些基因文库过程中没有发现其他的有意义的氨基酸序列,提示最后3个氨基酸(ts-X-V/L/I)基序对于与FAP-1的第三PDZ区域的结合非常重要,并且在蛋白-蛋白之间相互作用以及调节由Fas诱导的凋亡过程中起至关重要的作用。为了进一步确定是否这最后的3个氨基酸对于Fas/FAP-1的结合是必需的,而且足以满足其结合,我们构建了LexA-SLV,-PLV,-PLY,-SLY和-SLA融合蛋白的质粒,然后与PVP16-FAP-1共转化到酵母中。结果表明只有LexA-SLV与FAP-1结合,而LexA-PLV,-PLY,-SLY和-SLA不能结合(图4A)。用各种GST-三肽融合体研究体外结合和在体外翻译的FAP-1所得的结果是一致的(图4B)。
除了酵母双杂交系统外,也利用了Fas/FAP-1结合的体外抑制作用检测。首先,检测C-端15个氨基酸的合成肽是否能在体外抑制Fas和FAP-1的结合(图3A)。体外翻译的FAP-1与GST-Fas的结合也显著地降低而且与合成的FAS的15个氨基酸的浓度有关。与这些结果相比,在同样的生物化学条件下,人的PAMP肽(Kitamuta,等1994)作为阴性对照对Fas/FAP-1的结合活性没有影响。第二,检测截短的Fas C-末端合成肽对Fas/FAP-1体外结合的效应。正如图3B所示,对于Fas/FAP-1的结合,在C-端只有3个氨基酸(Ac-SLV)就足以得到与合成的4-15肽所起的抑制影响。进一步利用三肽的替换肽,研究Fas/FAP-1的结合,以决定对抑制作用所必须的重要的氨基酸(图3C)。这些结果揭示了C端的第三个氨基酸和C-末端氨基酸分别为丝氨酸或苏氨酸;以及缬氨酸,亮氨酸,或异亮氨酸时具有最强的抑制效应。但是C端第二个氨基酸中对于它们的Fas/FAP-1结合抑制效应没有显著差异。这些结果与酵母双杂交系统所得结果(图2C,2D)是一致的。因此,结论是C端的三个氨基酸(SLV)对于Fas与FAP-1蛋白的第三个PDZ区域结合是决定性的。
为了进一步研究在更天然条件下PDZ区域与ts/T-X-V/L./I之间相互作用的重要意义,我们检测了GST融合的FAP-1蛋白与JurkatT细胞表达的Fas相互作用的能力。结果揭示了是Ac-SLV三肽,而不是Ac-SLY三肽取消了FAP-1与从Jurkat T细胞中提取的Fas蛋白以剂量依赖的方式相结合的活性(图4C和4D)。这些结果揭示了C-端氨基酸tSLV对于FAP-1是最小的结合位点。而且丝氨酸和颉氨酸对于这种物理性的结合是至关重要的。
为了进一步验证这一推论,即FasC端的3个氨基酸与FAP-1第三个PDZ区域之间的物理结合对于体内FAP-1作为由Fas介导的信号传导的负调控因子的功能是必需的,应用微注射的实验,将合成的三肽注射到大肠癌细胞株DLD-1,该细胞株能表达Fas和FAP-1,并抵抗由Fas诱导的凋亡。这些实验包括直接将合成的三肽注射到单个细胞的胞浆,检测体内由Fas-诱导的凋亡的生理性反映。结果显示,将Ac-SLV微注射到DLD-1细胞时有Fas-单克隆抗体存在的情况下(CH11,500ng/ml),可以显著地诱导凋亡(图5A,5E,和图6),但是微注射Ac-S LY和PBS/K则不能诱导凋亡(图5B,5F和图6)。这些结果有力地支持了这种推论,即FAP-1与FasC端物理性结合对于防止细胞被Fas-诱导引起凋亡是必需的。
总之,我们发现了FasC端的SLV对于结合到FAP-1第三个PDZ区域是唯一必须的,并能满足其需要。第二,提出了新的tS/T-X-V/L/I的共用基序,而不是tS/T-X-V,被用于与PDZ区域的结合。因此很可能除了FAP-1与Fas物理性相互作用外,FAP-1在信号传导途径的调节作用中也起很重要的作用。第三,证明了在大肠癌细胞中直接注射三肽Ac-SLV可以定向地诱导由FaS-介导的凋亡。进一步的研究包括确定FAP-1的底物和结构功能的分析,在癌细胞中利用Fas/FAP-1的相互作用用于治疗以及提供证据更好地了解FAP-1对由Fas介导的信号传导的抑制作用。
第二部分实验
FAP-1原是鉴定为膜结合蛋白酪氨酸磷酸酶,它与Fas的C端相结合,有6个PDZ区域(也被称作DHR区域或GLGF重复)。最近研究表明PDZ区域是作为一种新的特异的蛋白-蛋白之间相互作用模件,而且看来在膜蛋白的装配,和在多蛋白的复合物中与信号分子连接的过程中起重要作用。
最近的综合研究结果发现FAP-1的第三个PDZ区域特异地识别一个序列基序t(S/T)-X-V,并与Fas的C-端3个氨基酸相互作用(图9)。为了研究FAP-1也与p75NGFR C端区域相互作用的可能性(图8),利用体外结合实验以及通过用酵母的双杂交系统将一系列的p75NGFR缺失突变后进行分析。结果揭示p75NGFR C-端胞浆部分与FAP-1相互作用,该p75NGFR C-端胞浆部分在所有的种类中是高度保守的(图10)。而且,p75NGFR C-端的三个氨基酸SPV是必须的,且足以满足与FAP-1的第三个PDZ区域都相互作用(图11A,11B)。由于FAP-1在胎儿脑的表达最高,所以这些结果暗示FAP-1与p75NGFR之间的相互作用在神经细胞中通过p75NGFR的途径进行信号传递的过程中以及在p75NGFR启始信号转变复合物的形成中起重要作用。
