One). The X residue differs in Each and every course of MAPKs: ERK includes a threonine–glutamic acid–tyrosine (T–E–Y) motif, JNK contains a threonine–proline–tyrosine (T–P–Y) motif and p38 includes a threonine–glycine–tyrosine (T–G–Y) motif. Phosphorylation in the T–X–Y motif activates the MAPKs, allowing phosphorylation of a particular repertoire of cytoplasmic and nuclear https://chamforti649mpc1.sasugawiki.com/user
