The Flt-1 (Phospho-Tyr1048) antibody detects the phosphorylated form of vascular endothelial growth factor receptor 1 (VEGFR-1/Flt-1) at tyrosine residue 1048. Flt-1. a receptor tyrosine kinase, binds VEGF-A, VEGF-B, and placental growth factor (PlGF), playing critical roles in angiogenesis, vascular permeability, and cellular migration. Tyrosine phosphorylation at specific residues, including Y1048. is a key regulatory mechanism for receptor activation and downstream signaling. Upon ligand binding, Flt-1 undergoes dimerization and autophosphorylation at intracellular tyrosine residues, creating docking sites for adaptor proteins (e.g., PLCγ, Shc) to initiate signaling cascades like MAPK and PI3K/Akt pathways. Phosphorylation at Y1048 is associated with receptor internalization and modulation of endothelial cell responses.
The Flt-1 (Phospho-Tyr1048) antibody is widely used in research to study VEGF signaling dynamics, particularly in pathological contexts like cancer, retinopathy, or preeclampsia, where dysregulated angiogenesis or Flt-1 shedding (sFlt-1) occurs. It helps assess Flt-1 activation status in tissues or cell models via techniques like Western blotting or immunofluorescence. Elevated phosphorylated Flt-1 levels may indicate hyperactive VEGF signaling, while reduced phosphorylation could reflect therapeutic inhibition. This antibody is also relevant in exploring crosstalk between Flt-1 and other VEGF receptors (e.g., VEGFR-2/KDR) or tyrosine kinase pathways in vascular biology and disease mechanisms.
