Hemangioblast Marker
Vascular endothelial growth factor (VEGF) is a major growth factor for endothelial cells. This gene encodes one of the two receptors of the VEGF. This receptor, known as kinase insert domain receptor, is a type III receptor tyrosine kinase. It functions as the main mediator of VEGF-induced endothelial proliferation, survival, migration, tubular morphogenesis and sprouting. The signalling and trafficking of this receptor are regulated by multiple factors, including Rab GTPase, P2Y purine nucleotide receptor, integrin alphaVbeta3, T-cell protein tyrosine phosphatase, etc.. Mutations of this gene are implicated in infantile capillary hemangiomas. [provided by RefSeq, May 2009].
Function:
Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFC and VEGFD. Plays an essential role in the regulation of angiogenesis, vascular development, vascular permeability, and embryonic hematopoiesis. Promotes proliferation, survival, migration and differentiation of endothelial cells. Promotes reorganization of the actin cytoskeleton. Isoforms lacking a transmembrane domain, such as isoform 2 and isoform 3, may function as decoy receptors for VEGFA, VEGFC and/or VEGFD. Isoform 2 plays an important role as negative regulator of VEGFA-and VEGFC-mediated lymphangiogenesis by limiting the amount of free VEGFA and/or VEGFC and preventing their binding to FLT4. Modulates FLT1 and FLT4 signaling by forming heterodimers. Binding of vascular growth factors to isoform 1 leads to the activation of several signaling cascades. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, reorganization of the actin cytoskeleton and activation of PTK2/FAK1. Required for VEGFA-mediated induction of NOS2 and NOS3, leading to the production of the signaling molecule nitric oxide (NO) by endothelial cells. Phosphorylates PLCG1. Promotes phosphorylation of FYN, NCK1, NOS3, PIK3R1, PTK2/FAK1 and SRC.
Subunit:
Interacts with MYOF (By similarity). Interacts with VEGFA, VEGFC and VEGFD. Monomer in the absence of bound VEGFA, VEGFC or VEGFD. Homodimer in the presence of bound dimeric VEGFA, VEGFC or VEGFD. Can also form heterodimers with FLT1 and FLT4. Interacts (tyrosine phosphorylated) with FYN, NCK1, PLCG1 and SHB. Interacts with HIV-1 Tat. Interacts with CBL. Interacts with SH2D2A/TSAD and GRB2.
Subcellular Location:
Isoform 1: Cell membrane; Single-pass type I membrane protein. Cytoplasm. Nucleus. Cytoplasmic vesicle. Early endosome. Note=Detected on caveolae-enriched lipid rafts at the cell surface. Is recycled from the plasma membrane to endosomes and back again. Phosphorylation triggered by VEGFA binding promotes internalization and subsequent degradation. VEGFA binding triggers internalization and translocation to the nucleus.
Isoform 2: Secreted (Probable).
Isoform 3: Secreted.
Tissue Specificity:
Detected in cornea (at protein level). Widely expressed.
Post-translational modifications:
N-glycosylated.
Ubiquitinated. Tyrosine phosphorylation of the receptor promotes its poly-ubiquitination, leading to its degradation via the proteasome or lysosomal proteases.
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-951 is important for interaction with SH2D2A/TSAD and VEGFA-mediated reorganization of the actin cytoskeleton. Phosphorylation at Tyr-1175 is important for interaction with PLCG1 and SHB. Phosphorylation at Tyr-1214 is important for interaction with NCK1 and FYN. Dephosphorylated by PTPRB. Dephosphorylated by PTPRJ at Tyr-951, Tyr-996, Tyr-1054, Tyr-1059, Tyr-1175 and Tyr-1214.
DISEASE:
Defects in KDR are associated with susceptibility to hemangioma capillary infantile (HCI) [MIM:602089]. HCI are benign, highly proliferative lesions involving aberrant localized growth of capillary endothelium. They are the most common tumor of infancy, occurring in up to 10% of all births. Hemangiomas tend to appear shortly after birth and show rapid neonatal growth for up to 12 months characterized by endothelial hypercellularity and increased numbers of mast cells. This phase is followed by slow involution at a rate of about 10% per year and replacement by fibrofatty stroma.
Note=Plays a major role in tumor angiogenesis. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions.

Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.

Ab）是由效应B细胞（效应**B细胞）分泌，机体用于抵御外来物质，如病毒，**等抗原，结构呈“Y”字型的球状蛋白质，仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质，均被称作抗原，因此对于抗抗体（能够结合抗体的抗体）来说，抗体本身也是一种抗原物质。
phospho-VEGFR2 (Tyr951)抗体普通抗体重链和轻链的结构
重链结构：普通的**球蛋白具有2条重链（H链），分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型，对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构： 普通**球蛋白具有2条轻链（L链），分子质量约25kDa，有κ链和λ链两种亚型，这两种轻链决定了Ig的亚型类别（IgG1，IgG2，IgG3，IgG4）。一个天然的Ig分子两条轻链总是相同的，但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同，正常人血清**球蛋白κ链：λ链约为2：1，而在小鼠的比例为20：1。
2.2抗体Fab段和Fc段
IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应；经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段（fragment of antigen binding，Fab），相当于抗体分子的两个臂，由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段（fragment crystallizable，Fc）相当于Ig的CH2和CH3结构域，是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区，以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域，相当于Y字结构下面那一部分。
