VEGFR1/FLT-1 概述&蛋白信息

VEGFR1/FLT-1 研究背景

基因概述: This FLT1 gene encodes a member of the vascular endothelial growth factor receptor (VEGFR) family. VEGFR family members are receptor tyrosine kinases (RTKs) which contain an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and a tyrosine kinase (TK) domain within the cytoplasmic domain. This FLT1 protein binds to VEGFR-A, VEGFR-B and placental growth factor and plays an important role in angiogenesis and vasculogenesis. Expression of this receptor is found in vascular endothelial cells, placental trophoblast cells and peripheral blood monocytes. Multiple transcript variants encoding different isoforms have been found for this FLT1 gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia.

催化活性: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. {ECO:0000255|PROSITE-ProRule:PRU10028, ECO:0000269|PubMed:11312102, ECO:0000269|PubMed:12796773, ECO:0000269|PubMed:7824266, ECO:0000269|PubMed:9299537, ECO:0000269|PubMed:9722576}.
酶调控: ENZYME REGULATION: Present in an inactive conformation in the absence of bound ligand. Binding of VEGFA, VEGFB or PGF leads to dimerization and activation by autophosphorylation on tyrosine residues.
亚单位结构: Interacts with VEGFA, VEGFB and PGF. Monomer in the absence of bound VEGFA, VEGFB or PGF. Homodimer in the presence of bound VEGFA, VEGFB and PGF. Can also form a heterodimer with KDR. Interacts (when tyrosine phosphorylated) with CBL, CRK, GRB2, NCK1, PIK3R1, PLCG, PSEN1 and PTPN11. Probably interacts also with PTPRB. Interacts with GNB2L1/RACK1. Identified in a complex with CBL and CD2AP. {ECO:0000269|PubMed:10471394, ECO:0000269|PubMed:10543948, ECO:0000269|PubMed:11312102, ECO:0000269|PubMed:11513746, ECO:0000269|PubMed:12796773, ECO:0000269|PubMed:14684734, ECO:0000269|PubMed:15001553, ECO:0000269|PubMed:20501651, ECO:0000269|PubMed:21212275, ECO:0000269|PubMed:22016384, ECO:0000269|PubMed:7824266, ECO:0000269|PubMed:8248162, ECO:0000269|PubMed:9299537, ECO:0000269|PubMed:9393862, ECO:0000269|PubMed:9600074, ECO:0000269|PubMed:9722576}.
结构域: The second and third Ig-like C2-type (immunoglobulin-like) domains are sufficient for VEGFA binding. {ECO:0000269|PubMed:20501651, ECO:0000269|PubMed:9393862}.
亚细胞定位: Isoform 1: Cell membrane; Single-pass type I membrane protein. Endosome. Note=Autophosphorylation promotes ubiquitination and endocytosis.; Isoform 2: Secreted {ECO:0000269|PubMed:8248162}.; Isoform 3: Secreted.; Isoform 4: Secreted.; Isoform 5: Cytoplasm {ECO:0000305}.; Isoform 6: Cytoplasm {ECO:0000305}.; Isoform 7: Cytoplasm {ECO:0000305}.
组织特异性: Detected in normal lung, but also in placenta, liver, kidney, heart and brain tissues. Specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. Isoform 2 is strongly expressed in placenta. Isoform 3 is expressed in corneal epithelial cells (at protein level). Isoform 3 is expressed in vascular smooth muscle cells (VSMC). {ECO:0000269|PubMed:18515749, ECO:0000269|PubMed:20512933}.
诱导: Up-regulated in coculture of VSMC/endothelial cell (EC) or by direct exposure to VEGF of VSMC monoculture. Up-regulated from the second trimester of pregnancy to the term and in the placenta of women with preeclampsia (PE). Up-regulated in monocytes exposed to bacterial lipopolysaccharide (LPS). {ECO:0000269|PubMed:18515749, ECO:0000269|PubMed:8605350}.
翻译后修饰: N-glycosylated. {ECO:0000269|PubMed:10471394, ECO:0000269|PubMed:11513746}.; Ubiquitinated after VEGFA-mediated autophosphorylation, leading to proteolytic degradation. {ECO:0000269|PubMed:15001553}.; Autophosphorylated on tyrosine residues upon ligand binding. Autophosphorylation occurs in trans, i.e. one subunit of the dimeric receptor phosphorylates tyrosine residues on the other subunit. Phosphorylation at Tyr-1169 is important for interaction with PLCG. Phosphorylation at Tyr-1213 is important for interaction with PIK3R1, PTPN11, GRB2, and PLCG. Phosphorylation at Tyr-1333 is important for endocytosis and for interaction with CBL, NCK1 and CRK. Is probably dephosphorylated by PTPRB. {ECO:0000269|PubMed:11513746, ECO:0000269|PubMed:12796773, ECO:0000269|PubMed:9299537, ECO:0000269|PubMed:9600074, ECO:0000269|PubMed:9722576}.
相关疾病 : DISEASE: Note=Can contribute to cancer cell survival, proliferation, migration, and invasion, and tumor angiogenesis and metastasis. May contribute to cancer pathogenesis by promoting inflammatory responses and recruitment of tumor-infiltrating macrophages.; DISEASE: Note=Abnormally high expression of soluble isoforms (isoform 2, isoform 3 or isoform 4) may be a cause of preeclampsia.
相似的序列: Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily. {ECO:0000255|PROSITE-ProRule:PRU00159}.; Contains 7 Ig-like C2-type (immunoglobulin-like) domains. {ECO:0000305}.; Contains 1 protein kinase domain. {ECO:0000255|PROSITE-ProRule:PRU00159}.
General information above from UniProt

Vascular endothelial growth factor receptor 1, also known as VEGFR-1, Fms-like tyrosine kinase 1, Tyrosine-protein kinase FRT, Tyrosine-protein kinase receptor FLT, Vascular permeability factor receptor and FLT1, is a single-pass type I membrane protein and secreted protein which belongs to the protein kinase superfamily, Tyr protein kinase family and CSF-1/PDGF receptor subfamily. VEGFR-1 / FLT1 contains seven Ig-like C2-type (immunoglobulin-like) domains and one protein kinase domain. VEGFR-1 / FLT1 is expressed mostly in normal lung, but also in placenta, liver, kidney, heart and brain tissues. It is specifically expressed in most of the vascular endothelial cells, and also expressed in peripheral blood monocytes. VEGFR-1 / FLT1 is not expressed in tumor cell lines. VEGFR-1 / FLT1 is an essential receptor tyrosine kinase that regulates mammalian vascular development and embryogenesis. EGF-induced angiogenesis requires inverse regulation of VEGFR-1 and VEGFR-2 in tumor-associated endothelial cells. VEGFR-1 / FLT1 is a receptor for VEGF, VEGFB and PGF. It has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability.
