功能May play a role in the control of cell motility and survival of macrophages (By similarity). Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the cortical actin filament dynamics and cell shape.
组织特异性Expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
序列相似性Belongs to the formin homology family. Contains 1 DAD (diaphanous autoregulatory) domain. Contains 1 FH2 (formin homology 2) domain. Contains 1 GBD/FH3 (Rho GTPase-binding/formin homology 3) domain.
结构域The DAD domain regulates activation via by an autoinhibitory interaction with the N-terminus. This autoinhibition is released upon competitive binding of an activated GTPase. The release of DAD allows the FH2 domain to then nucleate and elongate nonbranched actin filaments.
翻译后修饰Myristoylation mediates membrane localization and blebbing.
细胞定位Cytoplasm > cell cortex. Cell projection > bleb. Colocalized with F-actin in bleb protrusions and Cytoplasm. Cell membrane. Cytoplasmic vesicle > phagosome. Recruited to actin-rich phagosomes during phagocytosis. Translocates to the plasma membrane upon activation by RAC1.
