Protein kinase C, zeta (PKCζ), also known as PRKCZ, is a protein in humans that is encoded by the PRKCZ gene. The PRKCZ gene encodes at least two alternative transcripts, the full-length PKCζ and an N-terminal truncated form PKMζ. PKMζ is thought to be responsible for maintaining long-term memories in the brain. Atypical PKC (aPKC) isoforms [zeta (this enzyme) and lambda/iota] play important roles in insulin-stimulated glucose transport. Human adipocytes contain PKC-zeta, rather than PKC-lambda/iota, as their major aPKC. Inhibition of the PKCζ enzyme inhibits insulin-stimulated glucose transport while activation of PKCζ increases glucose transport.

Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA722773) at 1/2,000 dilution was used in 5% NFDM/TBST at 4℃ overnight. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1/50,000 dilution was used for 1 hour at room temperature.
