<p>The SAP (after SAF-A/B, Acinus and PIAS) motif is a putative DNA binding domain found in diverse nuclear proteins involved in chromosomal organisation [<cite idref="PUB00006479"/>], including in apoptosis [<cite idref="PUB00018262"/>]. In yeast, SAP is found in the most distal N-terminal region of E3 SUMO-protein ligase SIZ1, where it is involved in nuclear localization [<cite idref="PUB00043355"/>].</p> DNA-binding SAP
