Previous GeneCards Identifiers for YAF2 Gene
The protein encoded by this gene interacts with YY1, a zinc finger protein involved in negative regulation of muscle-restricted genes. This gene product itself contains a single N-terminal C2-X10-C2 zinc finger, and in contrast to YY1, is up-regulated during myogenic differentiation. It also facilitates proteolytic cleavage of YY1 by the calcium- activated protease, m-calpain, suggesting a mechanism by which this protein antagonizes the negative effect of YY1. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2010]

YAF2 (YY1 Associated Factor 2) is a Protein Coding gene. GO annotations related to this gene include transcription coactivator activity and transcription corepressor activity. An important paralog of this gene is RYBP.
UniProtKB/Swiss-Prot for YAF2 Gene
Binds to MYC and inhibits MYC-mediated transactivation. Also binds to MYCN and enhances MYCN-dependent transcriptional activation. Increases calpain 2-mediated proteolysis of YY1 in vitro. Component of the E2F6.com-1 complex, a repressive complex that methylates Lys-9 of histone H3, suggesting that it is involved in chromatin-remodeling.
