Zinc Finger, CW-Type With PWWP Domain Protein 2 (ZCWPW2)

ZCWPW2 Contains 1 CW-type zinc finger.Contains 1 PWWP domain. The zinc finger CW (zf-CW) domain is a motif of about 60 residues that is frequently found in proteins involved in epigenetic regulation.The zf-CW domain adopts a new fold in which a zinc ion is coordinated tetrahedrally by four conserved Cys ligand residues. The tertiary structure of the zf-CW domain partially resembles that adopted by the plant homeo domain (PHD) finger bound to the histone tail, suggesting that the zf-CW domain and the PHD finger have similar functions. The solution structure of the complex of the zf-CW domain with the histone H3 tail peptide (1-10) with trimethylated K4 clarified its binding mode. zf-CW domain as a member of the histone modification reader modules for epigenetic regulation.
