The CSNK1Dgene encodes the casein kinase I isoform deltaenzyme in humans.
This gene is a member of the caseinkinase I (CKI) gene family whose members have been implicated in the control of cytoplasmic and nuclear processes, including DNA replication and repair. The encoded protein is highly similar to the mouse and rat CK1 delta homologs. Two transcript variants encoding different isoforms have been found for this gene.
