Active Recombinant Human FLT1 Protein (27-328aa), C-hIgG tagged

• Cat.No.: FLT1-133H
• Product Overview: Recombinant human VEGFR1/Flt-1 (27-328aa), fused to hIgG-tag at C-terminus, was expressed in HEK293 cell and purified by using conventional chromatography techniques.

Specification

• Description: This 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 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 gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia.

Q&As

How is FLT1 linked to preeclampsia in pregnancy?

Elevated levels of soluble FLT1 have been associated with preeclampsia, a pregnancy complication. Soluble FLT1 acts as a decoy receptor, reducing the bioavailability of VEGF and contributing to vascular dysfunction.

How does FLT1 contribute to retinal diseases such as diabetic retinopathy?

FLT1 has been implicated in retinal diseases like diabetic retinopathy, where abnormal blood vessel growth can lead to vision impairment. Inhibiting FLT1 may help regulate angiogenesis in such conditions.

How is FLT1 expression regulated in the human body?

FLT1 expression is regulated by various factors, including VEGF itself, as well as hypoxia and inflammation. These factors influence the balance of angiogenic signaling.

Can FLT1 be a biomarker for certain diseases?

Yes, elevated levels of soluble FLT1 have been investigated as potential biomarkers for conditions like preeclampsia, cancer, and certain cardiovascular diseases.

Can FLT1 be targeted for anti-angiogenic therapy?

Yes, targeting FLT1 is a strategy for anti-angiogenic therapy. Inhibiting FLT1 can impede blood vessel formation, limiting the blood supply to tumors and potentially slowing their growth.
