1). The X residue is different in Each individual class of MAPKs: ERK contains a threonine–glutamic acid–tyrosine (T–E–Y) motif, JNK includes a threonine–proline–tyrosine (T–P–Y) motif and p38 features a threonine–glycine–tyrosine (T–G–Y) motif. Phosphorylation of the T–X–Y motif activates the MAPKs, letting phosphorylation of a certain repertoire of cytoplasmic and nuclear https://rogerf431ktv3.mdkblog.com/profile
