Description
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).

Background
GRB7 is an adaptor protein that interacts with receptor tyrosine kinases (RTKs) like HER2, VEGFR, and IGF1R, linking them to downstream signaling pathways such as Ras/MAPK, PI3K/Akt, and focal adhesion kinase (FAK). GRB7 contains SH2, PH, and proline-rich domains, enabling its localization to membranes and interactions with signaling molecules involved in cell migration, adhesion, and proliferation. GRB7 is highly expressed in cancers, particularly HER2-positive breast cancer, ovarian cancer, and esophageal carcinoma, where it promotes tumor progression, metastasis, and angiogenesis. It also regulates integrin-mediated signaling pathways, playing roles in cell spreading and cytoskeletal organization. GRB7 dysregulation is associated with poor clinical outcomes in cancer patients due to its role in enhancing cell motility and survival. Knockdown studies show reduced tumor cell invasion, highlighting its potential as a therapeutic target in metastatic cancers.
