Abstract

The present invention relates to compositions comprising RNA guides targeting CIITA, processes for characterizing the compositions, cells comprising the compositions, and methods of using the compositions. The invention provides a composition comprising an RNA guide, wherein the RNA guide comprises (i) a spacer sequence that is substantially complementary to a target sequence within a CIITA gene and (ii) a direct repeat sequence; wherein the target sequence is adjacent to a protospacer adjacent motif (PAM) comprising the sequence 5 '-NTTN-3'.
