Anti-myosin X antibodies are used in the immunodetection of the protein encoded by the MYO10 gene. In humans, the canonical protein has a reported length of 2058 amino acid residues and a mass of 237.3 kDa. Its subcellular localization is in the membrane and cytoplasm. Alternative splicing is reported to yield 3 different isoforms for this protein. It is ubiquitously expressed across many tissue types. A member of the Myosin protein family, it is known to be involved with the regulation of cell shape and signal transduction pathways. Other names for this target antigen include unconventional myosin-X, unconventional myosin-10, unconventionnal myosin-X, and MyoX.
