The SAF-A/B, Acinus, and PIAS (SAP) domain is a small, 35 amino acid motif named after SAF-A/B, Acinus and PIAS, three proteins that contain it.[1].The SAP domain sequence is found in various proteins involved in RNA processing, DNA repair, and chromatin organization[1]. The SAP domain is predicted to contain two to three amphipathic alpha helices[2][3]
