Protein attributes

Sequence length	443 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Probable serine/threonine protein kinase which may function redundantly with MPK1-independent branch of the PCK1 pathway that is presumed to be required for the tolerance to high temperatures and stauroporin. Ref.3
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Miscellaneous	Present with 1590 molecules/cell in log phase SD medium. Ref.4
Sequence similarities	Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 protein kinase domain.
