CAMK4

Introduction

Calcium/calmodulin-dependent protein kinase type IV is an enzyme that in humans is encoded by the CAMK4 gene.^[1]

The product of this gene belongs to the serine/threonine protein kinase family, and to the Ca²⁺/calmodulin-dependent protein kinase (CAMK) 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]
