Anti-SH3PXD2A antibodies are used in the immunodetection of the protein SH3 and PX domains 2A. In humans, the canonical protein has a reported length of 1133 amino acid residues and a mass of 125.3 kDa. Its subcellular localization is in the cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the SH3PXD2 protein family, SH3PXD2A is known to be an adapter protein involved in invadopodia and podosome formation, extracellular matrix degradation and invasiveness of some cancer cells. Synonyms for this target antigen include SH3MD1, TKS5, SH3 and PX domain-containing protein 2A, SH3 multiple domains 1, adapter protein TKS5, and FISH. SH3PXD2A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of SH3PXD2A antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
