Folr1 Gene Summary [Rat]

Predicted to enable folic acid binding activity; folic acid receptor activity; and signaling receptor activity. Predicted to be involved in several processes, including circulatory system development; nervous system development; and regulation of signal transduction. Predicted to act upstream of or within folic acid metabolic process. Located in brush border membrane. Human ortholog(s) of this gene implicated in cerebral folate receptor alpha deficiency. Orthologous to human FOLR1 (folate receptor alpha). [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 Folr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
