Flt1 Gene Summary [Rat]
Enables ATP binding activity; growth factor binding activity; and vascular endothelial growth factor receptor activity. Involved in several processes, including liver regeneration; negative regulation of vascular endothelial growth factor production; and positive regulation of cell population proliferation. Located in extracellular space. Used to study corneal neovascularization. Biomarker of breast cancer; liver cirrhosis; myocardial infarction; retinal disease (multiple); and vascular dementia. Human ortholog(s) of this gene implicated in Kuhnt-Junius degeneration; bronchopulmonary dysplasia; diabetic retinopathy; and pre-eclampsia. Orthologous to human FLT1 (fms related receptor tyrosine kinase 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Flt1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
