Growth factor receptor-bound protein 7

Gene

GRB7

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Adapter protein that interacts with the cytoplasmic domain of numerous receptor kinases and modulates down-stream signaling. Promotes activation of down-stream protein kinases, including STAT3, AKT1, MAPK1 and/or MAPK3. Promotes activation of HRAS. Plays a role in signal transduction in response to EGF. Plays a role in the regulation of cell proliferation and cell migration. Plays a role in the assembly and stability of RNA stress granules. Binds to the 5'UTR of target mRNA molecules and represses translation of target mRNA species, when not phosphorylated. Phosphorylation impairs RNA binding and promotes stress granule disassembly during recovery after cellular stress (By similarity).By similarity

Post-translational modificationi

Phosphorylated on serine and threonine residues in response to activation of receptor kinases. Phosphorylated on tyrosine residues by TEK/TIE2. Phosphorylated on tyrosine residues by PTK2/FAK1, and possibly also other kinases. Phosphorylation is enhanced by activation of receptor kinases by a cognate ligand. Tyrosine phosphorylation is essential for activation of down-stream protein kinases. Phosphorylation decreases affinity for target mRNA molecules (By similarity).By similarity
