Anti-SMPX antibodies are used in the immunodetection of the protein small muscle protein X-linked. In humans, the canonical protein has a reported length of 88 amino acid residues and a mass of 9.6 kDa. A member of the SMPX protein family, SMPX is reported to play a role in the regulatory network through which muscle cells coordinate their structural and functional states during growth, adaptation, and repair. The SMPX gene has been associated with the disease, Deafness. Synonyms for this target antigen include Csl, DFN6, DFNX4, MPD7, small muscular protein, and Chisel. SMPX gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some SMPX antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
