Molecular adapter that acts as a bridge between proteins, and which is involved skeletal muscle development (By similarity). Functions as signal transducer for MSTN during skeletal muscle regeneration and myogenesis (By similarity). May regulate chemotaxis of both macrophages and myoblasts by reorganising actin cytoskeleton, leading to more efficient lamellipodia formation via a PI3 kinase dependent pathway (By similarity). In contrast to AKIRIN2, not involved in nuclear import of proteasomes (PubMed:34711951). Widely expressed with the highest expression in heart, liver, placenta and peripheral blood leukocytes. 'Akiraka ni suru' means 'making things clear' in Japanese. The name is given based on the presence of the clear nuclear localization signal. Belongs to the akirin family.
