One). The X residue differs in Each and every 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 contains a threonine–glycine–tyrosine (T–G–Y) motif. Phosphorylation of the T–X–Y motif activates the MAPKs, allowing for phosphorylation of a specific repertoire of cytoplasmic and https://sel120-34ahcl11098.thenerdsblog.com/24781003/details-fiction-and-pbrm1-bd2-in-7
