Zinc finger proteins (ZNFs), such as ZNF208, bind DNA and, through this binding, regulate gene transcription. Most ZNFs contain conserved C2H2 motifs and are classified as Kruppel-type zinc fingers. A conserved protein motif, termed the Kruppel-associated box (KRAB) domain, mediates protein-protein interactions (Eichler et al., 1998 [PubMed 9724325]). See ZNF91 (MIM 603971) for further information on ZNFs.[supplied by OMIM, Aug 2009]
