CRY1 and CRY2 bind the unphosphorylated BMAL1:CLOCK (ARNTL:CLOCK) heterodimer (and by homology the BMAL1:NPAS2 (ARNTL:NPAS2) heterodimer) and prolong its half-life. The unphosphorylated BMAL1:CLOCK heterodimer only weakly activates transcription and is therefore believed to competitively reduce transcription by phosphorylated BMAL1:CLOCK heterodimer. The complex of unphosphorylated BMAL1:CLOCK with CRY may contain additional components and may traffic into the nucleus.
