NEZHA, or Calmodulin regulated spectrin associated protein family member 3, is a human gene encoded by CAMSAP3. It may also be known as: Calmodulin-regulated spectrin-associated protein 3; Protein Nezha; protein phosphatase 1, regulatory subunit 80; KIAA1543; PPP1R80; calmodulin regulated spectrin-associated protein family, member 3. The encoded protein has an amino acid length of 1249 and a mass of 134.8 kDa. NEZHA is a member of the CAMSAP1 family. Homologs of this gene exist in other organisms, including: Frog.
