A cytoplasmic adaptor protein involved in signal transduction from receptor tyrosine kinases, including MET and EGFR. Gab1 plays a role in cell growth, differentiation, and survival. Immunohistochemical detection of Gab1 can aid in studying tumors with dysregulated MET or EGFR signaling pathways, including certain carcinomas and sarcomas.
