PNCK encodes the human gene, Pregnancy up-regulated nonubiquitous CaM kinase. It may also be known as: Calcium/calmodulin-dependent protein kinase type 1B; CaM kinase I beta; CaM kinase IB; CaM-KI beta; CaMKI-beta; Pregnancy up-regulated non-ubiquitously-expressed CaM kinase; Calcium/calmodulin-dependent protein kinase type 1B ; BSTK3; CaMK1b. The encoded protein is an enzyme with an amino acid length of 343 and a mass of 38.5 kDa. PNCK is a member of the Protein kinase superfamily, CAMK Ser/Thr protein kinase family, CaMK subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
