Flrt3 Gene Summary [Rat]
Predicted to enable chemorepellent activity; fibroblast growth factor receptor binding activity; and protein homodimerization activity. Involved in neuron projection extension and response to axon injury. Acts upstream of or within axon guidance. Located in axon terminus and synaptic membrane. Human ortholog(s) of this gene implicated in hypogonadotropic hypogonadism 21 with or without anosmia. Orthologous to human FLRT3 (fibronectin leucine rich transmembrane protein 3).

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 Flrt3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
