WebOct 29, 2024 · Cryptochrome binds to a clock protein complex to start a feedback loop that controls the length of the clock. This illustration shows a “pocket” in the clock protein complex where binding of the “tail” of the cryptochrome protein helps regulate the timing of the biological clock. Credit: G. Carlo Parico WebNov 3, 2024 · The cryptochrome mutation causes a small segment on the “tail” of the protein to get left out, and Partch’s lab found that this changes how tightly cryptochrome binds to the CLOCK:BMAL1 complex. “The region that gets snipped out actually controls the activity of cryptochrome in a way that leads to a 24-hour clock,” Partch explained.
WebOct 30, 2024 · The mutation causes the “tail” of the cryptochrome protein to get left out. “The region that gets snipped out actually controls the activity of cryptochrome in a way that leads to a 24-hour clock,” writes study co-author, Carrie Partch. “Without it, cryptochrome binds more tightly and stretches out the length of the clock each day.”
