Capping protein, Arp2/3 and myosin-I linker protein 2 (CARMIL2)

Cell membrane-cytoskeleton-associated protein which plays a role in the regulation of actin polymerization in the barbed end of actin filaments. Prevents F-actin heterodimeric capping protein (CP) activity in the leading edges of migrating cells, and hence creates uncapped barbed ends and enhances actin polymerization (PubMed:26466680).

Plays a role in cell protrusion formations; involved in cell polarity, lamellipodial assembly, membrane ruffling and macropinosome formations (PubMed:19846667, PubMed:26578515, PubMed:26466680). Involved too in cell migration and invadopodia formation during wound healing (PubMed:19846667, PubMed:26578515, PubMed:26466680).
