Entrez Summary: This gene encodes a zinc finger protein containing a Kruppel-associated box (KRAB) A-box domain at its N-terminus, followed by fourteen contiguous C2H2 zinc finger domains and a degenerate zinc finger. The KRAB A-box showed weak transcriptional repressor activity in a reporter gene assay. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2016].
UniProt Summary: May be involved in transcriptional regulation as a weak repressor when alone, or a potent one when fused with a heterologous protein containing a KRAB B-domain.
