General annotation (Comments)

Function	Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway By similarity.
Subunit structure	Associates with activated Tyr-phosphorylated EGF receptors and PDGF receptors via its SH2 domain. Also associates to other cellular Tyr-phosphorylated proteins such as SIT1, IRS1, IRS4, SHC and LNK; probably via the concerted action of both its SH2 and SH3 domains. It also seems to interact with RAS in the signaling pathway leading to DNA synthesis. Binds to and translocates the guanine nucleotide exchange factors SOS. Interacts with phosphorylated TOM1L1 and MET. Interacts with the phosphorylated C-terminus of SH2B2. Interacts with phosphorylated SIT1, LAX1, LAT, LAT2 and LIME1 upon TCR and/or BCR activation. Interacts with PTPNS1, REPS2 and the syntrophin SNTA1. Interacts with REPS1 and PIK3C2B via its SH3 domains. Interacts with CBL and CBLB. Interacts with JUB By similarity. Interacts with SHB, INPP5D/SHIP1, SKAP1, SKAP2 and CLNK By similarity. Forms a complex with MUC1 and SOS1, through interaction of the SH3 domains SH2 domain with phosphorylated MUC1. Interacts with PRNP By similarity. Interacts with NISCH, RALGPS1 and with HCST By similarity. Interacts with GAPT and THEMIS By similarity.
Subcellular location	Golgi apparatus By similarity.
Tissue specificity	Wide tissue distribution. Ref.1
Domain	The SH3 domains mediate interaction with RALGPS1 and SHB By similarity.
Sequence similarities	Belongs to the GRB2/sem-5/DRK family. Contains 1 SH2 domain. Contains 2 SH3 domains.
