General annotation (Comments)

Function

Function in let-60 Ras signaling pathway; acts downstream of lin-45 raf kinase, but before the lin-1 gene product in controlling vulval cell differentiation.

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Cofactor

Magnesium By similarity.

Enzyme regulation

Activated by tyrosine and threonine phosphorylation By similarity.

Domain

The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.

Post-translational modification

Dually phosphorylated on Thr-256 and Tyr-258, which activates the enzyme By similarity.

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.

Contains 1 protein kinase domain.
