ab11934 was shown to react with VEGFR1 in wild-type A-375 cells in Western blot with loss of signal observed in a VEGFR1 knockout cell line. Wild-type A-375 and VEGFR1 knockout cell lysates were subjected to SDS-PAGE. Membranes were blocked in 5% milk in TBST for 1 hr before incubation with ab11934 overnight at 4 °C at a 1/500 dilution. Blots were incubated with secondary antibodies at 0.2 µg/mL before imaging.

Supplementary information

VEGF Receptor 1 also known as FLT-1 is a protein that plays a critical role in the regulation of angiogenesis. Its mass is approximately 180 kDa. FLT-1 is a receptor tyrosine kinase expressed mainly on the surface of endothelial cells but also in monocytes and macrophages. The receptor binds vascular endothelial growth factor (VEGF) and placental growth factor (PlGF) which initiates a series of signaling cascades important for vascular development and function.
Biological function summary

FLT-1 mediates important cellular responses such as cell migration and proliferation. Although it often functions in conjunction with other receptors like VEGFR-2 FLT-1 has unique binding affinities that modulate the availability of VEGF for other receptors. FLT-1 proteins as part of complex signaling networks actively contribute to maintaining vascular homeostasis and regulating blood vessel permeability.

Pathways

FLT-1 is an important component in the VEGF signaling pathway and also part of the PlGF/VEGF pathway. The receptor serves as a decoy to regulate the amount of VEGF interaction with VEGFR-2 influencing endothelial cell function and vascular permeability. By sequestering VEGF FLT-1 helps maintain the balance in this angiogenic signaling network interacting with proteins like VEGF PlGF and the anti-VEGF agents that target these pathways.

FLT-1 is implicated in cancer and diabetic retinopathy. Overexpression or dysregulation of FLT-1 can contribute to tumor angiogenesis which can enhance tumor growth and metastasis. In diabetic retinopathy abnormal FLT-1 activity affects retinal blood vessels leading to vision impairment. Similar interactions involve VEGFR-2 and other downstream effectors emphasizing the potential of FLT-1 as a therapeutic target for conditions associated with excessive angiogenesis and vascular dysfunction.

Target data

Tyrosine-protein kinase that acts as a cell-surface receptor for VEGFA, VEGFB and PGF, and plays an essential role in the development of embryonic vasculature, the regulation of angiogenesis, cell survival, cell migration, macrophage function, chemotaxis, and cancer cell invasion. Acts as a positive regulator of postnatal retinal hyaloid vessel regression (By similarity). May play an essential role as a negative regulator of embryonic angiogenesis by inhibiting excessive proliferation of endothelial cells. Can promote endothelial cell proliferation, survival and angiogenesis in adulthood. Its function in promoting cell proliferation seems to be cell-type specific. Promotes PGF-mediated proliferation of endothelial cells, proliferation of some types of cancer cells, but does not promote proliferation of normal fibroblasts (in vitro). Has very high affinity for VEGFA and relatively low protein kinase activity; may function as a negative regulator of VEGFA signaling by limiting the amount of free VEGFA and preventing its binding to KDR. Modulates KDR signaling by forming heterodimers with KDR. Ligand binding leads to the activation of several signaling cascades. Activation of PLCG leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate and the activation of protein kinase C. Mediates phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, leading to activation of phosphatidylinositol kinase and the downstream signaling pathway. Mediates activation of MAPK1/ERK2, MAPK3/ERK1 and the MAP kinase signaling pathway, as well as of the AKT1 signaling pathway. Phosphorylates SRC and YES1, and may also phosphorylate CBL. Promotes phosphorylation of AKT1 at 'Ser-473'. Promotes phosphorylation of PTK2/FAK1 (PubMed : 16685275).. Isoform 1. Phosphorylates PLCG.. Isoform 2. May function as decoy receptor for VEGFA.. Isoform 3. May function as decoy receptor for VEGFA.. Isoform 4. May function as decoy receptor for VEGFA.. Isoform 7. Has a truncated kinase domain; it increases phosphorylation of SRC at 'Tyr-418' by unknown means and promotes tumor cell invasion.
