LRRN4 (Leucine-rich repeat neuronal protein 4) is a type I transmembrane protein that is a member of the LRRN family. It is expressed in lung, heart, ovary, and neuronal tissues (1-3). Mature mouse LRRN4 is composed of a 657 amino acid (aa) extracellular domain (ECD) that includes ten LRRs, one LRRCT and a fibronectin type-III like domain, a 21 aa transmembrane segment, and a 36 aa cytoplasmic domain. Within the ECD, mouse LRRN4 shares 66% and 84% aa sequence identity with human and rat LRRN4, respectively. LRRN4-deficient mice show defects in the memory retention, suggesting this protein may play an important role in hippocampus-dependent long-lasting memory (1). In addition, LRRN4 is found in about 8% dorsal root ganglion (DRG) neurons (2). These neurons are small-sized neurons that function as nociceptors. LRRN4 expression was decreased in the DRG by sciatic axotomy suggesting that LRRN4 might function as a synaptic adhesion molecule to maintain nociceptive circuits (2). LRRN4 is also expressed in primary mesothelial cells and may be developed as a maker for detection of mesothelioma antigens (4).
