CSNK1A1 (Casein kinase I isoform alpha) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. In the public catalogues the evidence so far is association rather than a proven role. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Casein kinases are operationally defined by their preferential utilisation of acidic proteins such as caseins as substrates. Phosphorylates a large number of proteins. Participates in Wnt signalling. Phosphorylates CTNNB1 at 'Ser-45'. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis. Location: Cytoplasm; Cytoplasm, cytoskeleton, microtubule organizing center, centrosome; Chromosome, centromere, kinetochore; Nucleus speckle (UniProt). Locus 5q32 (HGNC).
