Transcription factor that binds to GC box promoter elements. Activates the transcription of these genes. Interacts with WWP1. Interacts with ANP32B; this interaction induces promoter region-specific histone incorporation and inhibition of histone acetylation by ANP32B. Expressed only in testis and placenta. The 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors. Ubiquitinated. Polyubiquitination involves WWP1 and leads to proteasomal degradation of this protein. Belongs to the krueppel C2H2-type zinc-finger protein family.
