Protein
Discs overgrown protein kinase
Organism
Drosophila melanogaster
Function
Involved in circadian rhythms, viability and molecular oscillations of the clock genes period (per) and timeless (tim). Dbt reduces the stability and thus the accumulation of monomeric per proteins, probably through phosphorylation. No evident circadian oscillation is detected in head. Together with CkIalpha, regulates processing of ci by phosphorylating it which promotes its binding to slmb, the F-box recognition component of the SCF(slmb) E3 ubiquitin-protein ligase (PubMed:16326393).
Similarity
Belongs to the protein kinase superfamily. CK1 Ser/Thr protein kinase family. Casein kinase I subfamily.
