Protein

Serine/threonine-protein kinase dkf-2

Gene

dkf-2

Organism
Caenorhabditis elegans
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Converts transient diacylglycerol (DAG) signals into prolonged physiological effects, downstream of PKC. Acts in the intestine to regulate both innate immunity by promoting activation of PMK-1 and also stress response and life span by acting as an upstream, negative regulator of the daf-16 transcription factor.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.2 Publications

Cofactori

Mg2+2 Publications

Enzyme regulationi

Activated by DAG and phorbol esters. Phorbol-ester/DAG-type domain 1 binds phorbol ester with low affinity. Phorbol-ester/DAG-type domain 2 binds phorbol ester with high affinity and targets the kinase to the cell periphery, enabling phosphorylation and activation by colocalized tpa-1. Both domains 1 and 2 appear to bind DAG with equal affinity so may contribute equally to translocation and activation.2 Publications

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
