CSNK1D
Casein kinase I isoform delta also known as CKI-delta or CK1δ is an enzyme that in humans is encoded by the gene CSNK1D, which is located on chromosome 17 (17q25.3). It is a member of the CK1 (formerly named casein kinase 1) family of serine/threonine specific eukaryotic protein kinases encompassing seven distinct isoforms (CK1α, γ1-3, δ, ε) as well as various post-transcriptionally processed splice variants (transcription variants, TVs) in mammalians. Meanwhile, CK1δ homologous proteins have been isolated from organisms like yeast, basidiomycetes, plants, algae, and protozoa.
