Overview
CNP May participate in RNA metabolism in the myelinating cell, CNP is the third most abundant protein in central nervous system myelin. Exists as monomers and homodimers. Belongs to the cyclic nucleotide phosphodiesterase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
