SH2B adapter protein 2

Gene

SH2B2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Adapter protein for several members of the tyrosine kinase receptor family. Involved in multiple signaling pathways. May be involved in coupling from immunoreceptor to Ras signaling. Acts as a negative regulator of cytokine signaling in collaboration with CBL. Binds to EPOR and suppresses EPO-induced STAT5 activation, possibly through a masking effect on STAT5 docking sites in EPOR. Suppresses PDGF-induced mitogenesis. May induce cytoskeletal reorganization via interaction with VAV3.4 Publications

Interactioni

Subunit structurei

Homodimer. Interacts with KIT/c-KIT, SHC1, EPOR, PDGFR, VAV1 and VAV3. Interacts (via N-terminal region) with SHC1. Interacts (via the phosphorylated C-terminus) with GRB2. Interacts (via its SH2 domain) with EPOR, INSR and KIT. Interacts with GRB2 after B-cell antigen receptor stimulation. Interacts (via PH domain) with VAV3. Interacts with NTRK1, NTRK2 and NTRK3 (phosphorylated); after stimulation of the receptor by its extracellular ligand and subsequent autophosphorylation of the receptor. Binds INSR, GRB2, ASB6 and CAP. Insulin stimulation leads to dissociation of CAP. Binds CBS only when SH2B2/APS has become phosphorylated. INSR binding does not depend on the phosphorylation of SH2B2/APS (By similarity).By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
