Neurochondrin (also known as its murine homologue, Norbin) is a protein that in humans is encoded by the NCDNgene.[1][2]
This gene encodes a leucine-rich cytoplasmic protein, which is highly similar to a mouse protein norbin that negatively regulates Ca/calmodulin-dependent protein kinase II phosphorylation and may be essential for spatial learning processes. Several alternatively spliced transcript variants of this gene have been described.[2]
Norbin can modulate signaling activity and expression of metabotropic glutamate receptor 5; modulating mice with targeted deletion of NCDN in the brain have phenotypic traits usually found in the rodent models of schizophrenia, including disruptions in prepulse inhibition.[3] Furthermore, norbin protein expression is altered in the schizophrenia brain.[4]
