WebCRY2 functions similarly to the mammalian CRY1 and CRY2 proteins in that it functions as one of the major repressors in the monarch TTFL. In the core loop of the monarch clock mechanism, the proteins CLOCK (CLK) and BMAL1 function as heterodimeric transcription factors that drive transcription of the period (per), timeless (tim), and cry2 genes.
