Probable regulator of cytoskeletal architecture that plays an important role in development. May regulate cellular and cytoskeletal architecture by modulating the spatial distribution of myosin II. Interacts directly with F-actin. Shows partial colocalization with the cytoplasmic pool of F-actin. Detected in most adult tissues examined. Expressed in brain, lung, heart, liver, kidney, muscle and ovary. Expressed throughout the brain, with high expression in the brain stem and cerebellum and weaker expression in the hypothalamus, the hippocampus and the olfactory bulb. Expressed in wide range of cell types during developpment, including vascular endothelium and the polarized epithelium of the neural tube and kidney. Slight expression at 8.5 dpc, increasing till 11.5 dpc and remaining continuous thereafter, suggesting regulated expression during development. Belongs to the shroom family.
