Bioinformation

Swiss-port # P08922 Human Proto-oncogene tyrosine-protein kinase ROS |
|---|---|
| Gene Symbol | ROS1 |
| Gene Full Name | ROS proto-oncogene 1 , receptor tyrosine kinase |
| Background | This proto-oncogene, highly-expressed in a variety of tumor cell lines, belongs to the sevenless subfamily of tyrosine kinase insulin receptor genes. The protein encoded by this gene is a type I integral membrane protein with tyrosine kinase activity. The protein may function as a growth or differentiation factor receptor. [provided by RefSeq, Jul 2008] |
| Function | Orphan receptor tyrosine kinase (RTK) that plays a role in epithelial cell differentiation and regionalization of the proximal epididymal epithelium. May activate several downstream signaling pathways related to cell differentiation, proliferation, growth and survival including the PI3 kinase-mTOR signaling pathway. Mediates the phosphorylation of PTPN11, an activator of this pathway. May also phosphorylate and activate the transcription factor STAT3 to control anchorage-independent cell growth. Mediates the phosphorylation and the activation of VAV3, a guanine nucleotide exchange factor regulating cell morphology. May activate other downstream signaling proteins including AKT1, MAPK1, MAPK3, IRS1 and PLCG2. [UniProt] |
| Cellular Localization | Cell membrane; Single-pass type I membrane protein |
| Research Area | Cancer antibody; Gene Regulation antibody; Signaling Transduction antibody |
| Calculated MW | 264 kDa |
| PTM | Phosphorylated. Probably autophosphorylates. Phosphorylation at Tyr-2274 is required for the interaction with PTPN6 that mediates ROS1 dephosphorylation (By similarity). Phosphorylation at Tyr-2274 stimulates the kinase activity and the activation of the ERK1 signaling cascade (By similarity). Phosphorylation at Tyr-2274 and/or Tyr-2334 recruits PTPN11. |
