[MYO5_YEAST] One of two redundant type-I myosins implicated in the organization of the actin cytoskeleton. Required for proper actin cytoskeleton polarization and for the internalization step in endocytosis. At the cell cortex, assembles in patch-like structures together with proteins from the actin-polymerizing machinery and promotes actin assembly. Functions redundantly with LAS17 as actin nucleation-promoting factor (NPF) for the Arp2/3 complex. Motor domain phosphorylation by PAK kinases CLA4 and STE20 promotes CDC42-regulated actin assembly. Functions together with the NPF PAN1 in late stages of endocytosis. Motor domain phosphorylation by PDK1 kinases PKH1 and PKH2, and by SGK kinases YPK1 and YPK2, promotes ligand-induced, but not constitutive endocytosis of the G protein-coupled receptor STE2.[1][2][3][4][5][6][7][8][9]
