Background: ERK7 (Extracellular signal-regulated kinase also known as ERK8 or MAPK15) is a most recently identified member of the mitogen-activated protein (MAP) kinase family which is evolutionarily conserved throughout the animal kingdom. Unlike other members of the ERK family, it has constitutive activity and typical activators of other MAPKs fail to further increase ERK7's activity. ERK7 is required for proliferating cell nuclear antigen (PCNA) protein stability and, thus, for the maintenance of genomic integrity and is involved in response to amino-acid starvation and autophagy. An overexpression of ERK7 is correlated to transformation of human colon cancer cells.
