Summary: 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 myoblast fusion. 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, Apr 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
