LRRN3 encodes the human gene, Leucine rich repeat neuronal 3. It may also be known as: Neuronal leucine-rich repeat protein 3; NLRR-3; Leucine-rich repeat neuronal protein 3; fibronectin type III, immunoglobulin and leucine rich repeat domains 5; FIGLER5; NLRR3. The encoded protein has an amino acid length of 708 and a mass of 79.4 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog, Chicken.
