Human NrCAM Antibody

NgCAM related cell adhesion molecule (NrCAM), also known as Bravo, belongs to the L1 family of cell adhesion molecules, which also include L1, neurofascin and close homolog of L1 (CHL-1) (1). These molecules are type I transmembrane proteins that have 6 Ig-like domains and 4 - 5 fibronectin type III-like domains in their extracellular domain. They also shared a conserved cytoplasmic region containing an ankyrin-binding site. L1 family cell adhesion molecules are expressed primarily in the nervous system where they share overlapping functions in controlling axonal growth and guidance (1, 2). NrCam mediates homophilic adhesion as well as heterophilic adhesion with a number of neuronal adhesion molecules including contactin, TAG-1/contactin-2, neurofascin and receptor tyrosine phosphatase beta (RPTP beta) (3 - 5). NrCAM has been implicated in the axogenesis of multiple neuronal populations including sensory axons and commissural axons in the spinal cord of chick embryos. It also plays a role in cerebellar granule cell development, and is required in node of Ranvier formation (5, 6).
