Myh9 Gene Summary [Mouse]
Enables actin filament binding activity and protein domain specific binding activity. Involved in several processes, including cortical granule exocytosis; negative regulation of actin filament severing; and positive regulation of protein processing in phagocytic vesicle. Acts upstream of or within several processes, including establishment of T cell polarity; microtubule cytoskeleton organization; and plasma membrane repair. Located in several cellular components, including cortical granule; cytoskeleton; and immunological synapse. Part of myosin II complex. Colocalizes with focal adhesion. Is expressed in several structures, including alimentary system; early embryo; genitourinary system; heart and pericardium; and sensory organ. Used to study MYH-9 related disease. Human ortholog(s) of this gene implicated in several diseases, including auditory system disease (multiple); autosomal dominant Alport syndrome; blood platelet disease (multiple); end stage renal disease; and orofacial cleft. Orthologous to human MYH9 (myosin heavy chain 9). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Myh9 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
