What is the function of this protein?
Serine/threonine-protein kinase which is an important downstream effector of CDC42 and plays a role in the regulation of cytoskeleton reorganization and cell migration (PubMed:9418861).  Regulates actin cytoskeletal reorganization via phosphorylation of PPP1R12A and MYL9/MLC2 (PubMed:21457715).  In concert with MYO18A and LURAP1, is involved in modulating lamellar actomyosin retrograde flow that is crucial to cell protrusion and migration (PubMed:18854160).  Phosphorylates: PPP1R12C, LIMK1 and LIMK2.  May play a role in TFRC-mediated iron uptake.  In concert with FAM89B/LRAP25 mediates the targeting of LIMK1 to the lamellipodium resulting in its activation and subsequent phosphorylation of CFL1 which is important for lamellipodial F-actin regulation (By similarity).  Triggers the formation of an extrusion apical actin ring required for epithelial extrusion of apoptotic cells (By similarity).
What are the official names of this protein?
Serine/threonine-protein kinase MRCK alpha, CDC42-binding protein kinase alpha, Myotonic dystrophy kinase-related CDC42-binding kinase alpha, MRCK alpha, Myotonic dystrophy protein kinase-like alpha.
What is the protein family that this protein belongs to?
Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. DMPK subfamily.
What are the subcellular locations of this protein?
Cytoplasm. Cell projection, lamellipodium. Note=Displays a dispersed punctate distribution and concentrates along the cell periphery, especially at the leading edge and cell-cell junction. This concentration is PH-domain dependent (PubMed:9418861). Localizes in the lamellipodium in a FAM89B/LRAP25-dependent manner (By similarity).
