SHB (SH2 homology protein in B/ beta -cells) is a 55-59 kDa cytoplasmic adaptor protein that serves as a link between phosphotyrosine residues and downstream signaling pathways. SHB is ubiquitously expressed, and binds tyrosine kinase receptors such as FGFR1, VEGFR2, and the TCR ( zeta -chain) following their activation. It is highly modular, and through a variety of motifs, is able to bind multiple, structurally unrelated proteins that collectively generate a signal transduction network. Human SHB is 509 amino acids (aa) in length. It contains an N-terminal Pro-rich region that binds SH3 domain-containing proteins (aa 19-45), a central PTB domain that binds select aa motifs, and a C-terminal SH2 domain that interacts with phosphotyrosines (aa 410-504). There are at least nine utilized phosphorylation sites. There are two isoform variants. One is 66-68 kDa in size, and possesses an 87 aa Pro-rich N-terminal extension. This MW may increase to 77-80 kDa following posttranslational processing. A second variant shows an 18 aa substitution for aa 280-509. Over aa 2-128, human SHB shares 91% aa identity with mouse SHB.
Phospho-Shb (Y246) Polyclonal Antibody detects endogenous levels of Shb protein only when phosphorylated at Y246.
Optimal working dilutions should be determined experimentally by the investigator. Suggested starting dilutions are as follows: WB: 1:500-1:2000, ELISA: 1:10000. Not yet tested in other applications.
