Gene ID: 9575 | Gene type: protein coding

About CLOCK

Cytogenetic location: 4q12 Genomic coordinates (GRCh38): 4:55,427,903-55,546,909 (from NCBI)

This gene has 11 transcripts (splice variants), 269 orthologues and 6 paralogues. Ubiquitous expression in testis (RPKM 7.8), thyroid (RPKM 6.2) and 24 other tissues.

Summary

The protein encoded by this gene plays a central role in the regulation of circadian rhythms. The protein encodes a transcription factor of the basic helix-loop-helix (bHLH) family and contains DNA binding Histone Acetyltransferase activity. The encoded protein forms a heterodimer with ARNTL (BMAL1) that binds E-box enhancer elements upstream of Period (PER1, PER2, PER3) and Cryptochrome (CRY1, CRY2) genes and activates transcription of these genes. PER and CRY proteins heterodimerize and repress their own transcription by interacting in a feedback loop with CLOCK/ARNTL complexes. Polymorphisms in this gene may be associated with behavioral changes in certain populations and with obesity and metabolic syndrome. Alternative splicing results in multiple transcript variants.
