Transcription regulator which may participate in NGFR/p75(NTR)-mediated apoptosis. Probably acts as a 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 (By similarity). Interacts with NGFR/p75(NTR). Ubiquitously expressed. Up-regulated in Nrif1 mutant mice in the 129/Sv background, possibly complementating for the absence of Nrif1 and explaining why Nrif1 mutant mice are viable in a 129/Sv background, whilke they are lethal in other backgrounds. Belongs to the krueppel C2H2-type zinc-finger protein family.
