Stk19

Stk19
PFAM accession number:PF10494
Interpro abstract (IPR018865):

This serine-threonine protein kinase number 19 is expressed from the MHC and predominantly in the nucleus. Protein kinases are involved in signal transduction pathways and play fundamental roles in the regulation of cell functions. This is a novel Ser/Thr protein kinase, that has Mn2+-dependent protein kinase activity that phosphorylates alpha -casein at Ser/Thr residues and histone at Ser residues. It can be covalently modified by the reactive ATP analogue 5'-p-fluorosulphonylbenzoyladenosine in the absence of ATP, and this modification is prevented in the presence of 1 mM ATP, indicating that the kinase domain of is capable of binding ATP [ (PUBMED:9812991) ].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Stk19
