Myosin-4 (UniProt: Q5SX39; also known as Myosin heavy chain 2b, MyHC-2B, Myosin heavy chain 4) is encoded by the Myh4 gene (Gene ID: 17884) in murine species. Muscle myosin is a hexameric protein that consists of 2 heavy chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2 regulatory light chain subunits (MLC-2). Limited proteolysis of myosin heavy chain produces 1 light meromyosin (LMM) and 1 heavy meromyosin (HMM). HMM can be further cleaved into 2 globular sub-fragments (S1) and 1 rod-shaped sub-fragment (S2). In mammals at least 10 different myosin heavy chain (MYH) isoforms have been described from striated, smooth, and non-muscle cells. These isoforms show expression that is spatially and temporally regulated during development. Myosin-4 contains an N-terminal SH3-like domain (aa 33-82), a myosin motor domain (aa 86-782), and an IQ domain (aa 785-814). It also contains 2 actin binding regions (aa 659-681 and 761-775).
