name: mitogen-activated protein kinase 1 sequence variant S142L, initiator methionine removed phosphorylated 1 (human)
def: "A mitogen-activated protein kinase 1 (human) that has a Leu residue at the position equivalent to Ser-142 of the amino acid sequence represented by UniProtKB:P28482-1, that has had the initiator methionine removed, and that has been phosphorylated on the residues at the positions equivalent to Thr-185 and Tyr-187.
