Anti-KAT13D/CLOCK Antibody Picoband® APC Conjugated

Clock (Circadian Locomotor Output Cycles Kaput) is also known as KAT13D. The protein encoded by this gene plays a central role in the regulation of circadian rhythms. This protein encodes a transcription factor of the basic helix-loop-helix (bHLH) family and contains DNA binding histone acetyltransferase activity. And 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.

A synthetic peptide corresponding to a sequence at the N-terminus of human KAT13D/CLOCK, different from the related mouse sequence by one amino acid, and identical to the related rat sequence.
