SH2B2

SH2B adapter protein 2 is a is_associated_with::protein that in humans is encoded by the SH2B2 is_associated_with::gene.

Function
The protein encoded by this gene is expressed in B lymphocytes and contains pleckstrin homology and src homology 2 (SH2) domains. In Burkitt lymphoma cell lines, it is tyrosine phosphorylated in response to B cell receptor stimulation. Because it binds Shc independent of stimulation and Grb2 after stimulation, it appears to play a role in signal transduction from the receptor to Shc/Grb2.

Interactions
SH2B2 has been shown to interact with is_associated_with::TrkA and is_associated_with::Cbl gene.
