an adaptor protein with an SH2-SH3-SH3 domain structure. Recruits cytoplasmic proteins through SH2-phospho-tyrosine interaction. Phosphorylated by Abl, IGF-IR and EGFR. Phosphorylation induces a change in intramolecular folding and SH2 interactions, causing its rapid dissociation from the tyrosine kinase complex. Note: This description may include information from UniProtKB.
