Calcium/calmodulin-dependent protein kinase type IV is an enzyme that in humans is encoded by the CAMK4gene.[1]
The product of this gene belongs to the serine/threonine protein kinase family, and to the Ca2+/calmodulin-dependent protein kinase subfamily. This enzyme is a multifunctional serine/threonine protein kinase with limited tissue distribution, that has been implicated in transcriptional regulation in lymphocytes, neurons and male germ cells.[2]
