Question

Quizplus · Accepted Answer

MAP kinase kinase is phosphorylated by another kinase called MAP kinase kinase kinase, also known as MAP3K. Once MAP kinase kinase kinase phosphorylates MAP kinase kinase, the latter then goes on to phosphorylate MAP kinase. This sequential activation is part of the MAP kinase signaling pathway, which regulates various cellular processes including gene expression, cell growth, and differentiation.
