Zinc Finger Protein 783 (ZNF783)

ZNF783 Contains 1 KRAB domain.The Krueppel-associated box (KRAB) is a domain of around 75 amino acids that is found in the N-terminal part of about one third of eukaryotic Krueppel-type C2H2 zinc finger proteins (ZFPs) . It is enriched in charged amino acids and can be divided into subregions A and B, which are predicted to fold into two amphipathic alpha-helices. The KRAB A and B boxes can be separated by variable spacer segments and many KRAB proteins contain only the A box. KRAB-ZFPs probably constitute the single largest class of transcription factors within the human genome. Although the function of KRAB-ZFPs is largely unknown, they appear to play important roles during cell differentiation and development. The KRAB domain is generally encoded by two exons. The regions coded by the two exons are known as KRAB-A and KRAB-B.
