Dual specificity mitogen-activated protein kinase kinase 7, also known as MAP kinase kinase 7 or MKK7, is an enzyme that in humans is encoded by the MAP2K7gene.[5] This protein is a member of the mitogen-activated protein kinase kinase family. The MKK7 protein exists as six different isoforms with three possible N-termini (α, β, and γ isoforms) and two possible C-termini (1 and 2 isoforms).[6]
MKK7 is ubiquitously expressed in all tissue. However, it displays a higher level of expression in skeletal muscle.[7] Multiple alternatively spliced transcript variants encoding distinct isoforms have been found.[5]
