This gene is a member of the casein kinase 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 may also be involved in the regulation of apoptosis, circadian rhythm, microtubule dynamics, chromosome segregation, and p53-mediated effects on growth. The encoded protein is highly similar to the mouse and rat CK1 delta homologs. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2014]
Forensic Context
A study in humans demonstrated that the CSNK1D is a differentially expressed circadian rhythm-related gene in sepsis, showing no significant expression difference between sepsis patients and healthy controls in RT-qPCR validation [Wang et al. DOI:10.3390/ijms26093993]. Another human study identified the CSNK1D as an upregulated mRNA biomarker in salivary extracellular vesicles from acute head trauma patients compared to controls, with significant differential expression also observed between emergency department patients and outpatient concussion clinic patients [Cheng et al. DOI:10.1002/jcp.28139].
