Description
This protein is expressed in B lymphocytes and contains pleckstrin homology and src homology 2 (SH2) domains. In Burkitt s 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 the Shc
Grb2 pathway
