Enzyme Information

2.7.11.1

Non-specific serine/threonine protein kinase.

based on mapping to UniProt O14757

ATP + a protein = ADP + a phosphoprotein.

-!- This is a heterogeneous group of serine/threonine protein kinases that do not have an activating compound and are either non-specific or their specificity has not been analyzed to date. -!- Formerly EC 2.7.1.37 and EC 2.7.1.70.
