ID:GRB14_HUMAN DESCRIPTION: RecName: Full=Growth factor receptor-bound protein 14; AltName: Full=GRB14 adapter protein; FUNCTION: Adapter protein which modulates coupling of cell surface receptor kinases with specific signaling pathways. Binds to, and suppresses signals from, the activated insulin receptor (INSR). Potent inhibitor of insulin-stimulated MAPK3 phosphorylation. Plays a critical role regulating PDPK1 membrane translocation in response to insulin stimulation and serves as an adapter protein to recruit PDPK1 to activated insulin receptor, thus promoting PKB/AKT1 phosphorylation and transduction of the insulin signal. SUBUNIT: Interacts with the cytoplasmic domain of the autophosphorylated insulin receptor (INSR), through the SH2 domain (By similarity). Interacts with GRB14 (via BPS domain); this interaction protects the tyrosines in the activation loop on INSR from dephosphorylation. Binds to the ankyrin repeat region of TNKS2 via its N-terminus. Interacts with activated NRAS. Interacts (via SH2 domain) with TEK/TIE2 (tyrosine phosphorylated). SUBCELLULAR LOCATION: Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Note=Upon insulin stimulation, translocates to the plasma membrane. TISSUE SPECIFICITY: Expressed at high levels in the liver, kidney, pancreas, testis, ovary, heart and skeletal muscle. DOMAIN: The PH domain binds relatively non-specifically and with low affinity to several phosphoinositides, the best binder being PI(3,4,5)P3. PTM: Phosphorylated on serine residues. Phosphorylated on tyrosine residues by TEK/TIE2. SIMILARITY: Belongs to the GRB7/10/14 family. SIMILARITY: Contains 1 PH domain. SIMILARITY: Contains 1 Ras-associating domain. SIMILARITY: Contains 1 SH2 domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
