Anti-NCK2 antibodies are used in the immunodetection of the protein NCK adaptor protein 2. In humans, the canonical protein has a reported length of 380 amino acid residues and a mass of 42.9 kDa. Its subcellular localization is in the ER and cytoplasm. It is ubiquitously expressed across many tissue types. NCK2 is reported to be an adapter protein, which associates with tyrosine-phosphorylated growth factor receptors or their cellular substrates. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include NCKbeta, cytoplasmic protein NCK2, SH2/SH3 adaptor protein NCK-beta, growth factor receptor-bound protein 4, noncatalytic region of tyrosine kinase, beta, and GRB4. NCK2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of NCK2 antibodies have been mentioned in research publications and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
