Probable transcription repressor. Specifically binds to the 3'-end of zinc-finger coding genes and recruiting chromatin-modifying proteins such as SETDB1 and TRIM28/KAP1, leading to transcription repression. The SETDB1-TRIM28-ZNF274 complex may play a role in recruiting ATRX to the 3'-exons of zinc-finger coding genes with atypical chromatin signatures to establish or maintain/protect H3K9me3 at these transcriptionally active regions (By similarity). Interacts with SETDB1 and TRIM28/KAP1. Interacts with ATRX. Forms a complex with ATRX, SETDB1 and TRIM28. Belongs to the krueppel C2H2-type zinc-finger protein family.
