p16-ARC, also known as ARPC5, is a 151 amino acid subunit of the Arp2/3 complex. Thought to play a role in maintaining the integrity of Arp2/3, ARPC5 is a substrate for MAPKAPK-2 which, through phosphorylation of ARPC5, may participate in Arp2/3 regulatory functions and remodeling of the Actin cytoskeleton. Two isoforms of ARPC5 exist due to alternative splicing events. Purified by using conventional chromatography techniques.
