Anti-TEC antibodies are used in the immunodetection of the protein tec protein tyrosine kinase. In humans, the canonical protein has a reported length of 631 amino acid residues and a mass of 73.6 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is reported to be expressed in a wide range of cells, including hematopoietic cell lines like myeloid, B-, and T-cell lineages. A member of the Tyr protein kinase protein family, TEC is a type of non-receptor tyrosine kinase that contributes to signaling from many receptors and participates as a signal transducer in multiple downstream pathways, including regulation of the actin cytoskeleton. Synonyms for this target antigen include PSCTK4 and tyrosine-protein kinase Tec. TEC gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TEC antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
