Transcription factor that binds to the CACCC box in the promoter of target genes such as HBB/beta globin or NOV and activates their transcription. Might be involved in transcriptional regulation by modulating the binding of the RARA nuclear receptor to RARE DNA elements (By similarity). Interacts with WWP1. Predominant expression in the lungs and spleen. 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.
