PIK3R4 Products

Phosphoinositide-3-Kinase, Regulatory Subunit 3 (PIK3R4), also known as Vacuolar Protein Sorting 15 (Vps15), is a 1358 amino acid (aa) protein with a predicted molecular weight of approximately 150 kDa. The human protein shares 96% aa sequence identity with the mouse and rat orthologs. Myristoylated PIK3R4 associates with membranes and regulates the activity of hVps34, the catalytic component of PI 3-Kinase complexes that catalyze the formation of phosphatidylinositol 3-phosphate [PI(3)P].
