SAP30 is a subunit of the histone deacetylase complex, and this domain is a zinc-finger. Solution of the structure shows a novel fold comprising two beta-strands and two alpha-helices with the zinc organising centre showing remote resemblance to the treble clef motif. In silico analysis of the structure revealed a highly conserved surface dominated by basic residues. NMR-based analysis of potential ligands for the SAP30 zn-finger motif indicated a strong preference for nucleic acid substrates. The zinc-finger of SAP3 probably functions as a double-stranded DNA-binding motif, thereby expanding the known functions of both SAP30 and the mammalian Sin3 co-repressor complex. Length = 68

Proteins in this family are involved in non-homologous end joining, a process used for the repair of double stranded DNA breaks. This family is based on the phylogenomic analysis of JA Eisen (1999, Ph.D. Thesis, Stanford University). Cutoff does not detect the putative ku70 homologs in yeast.
