CRY proteins

CRY proteins, short for cryptochromes, are a type of protein involved in regulating our biological clock or circadian rhythm—the internal process that controls sleep-wake cycles. They help synchronize our daily activities with the natural light-dark cycle by responding to light signals and influencing gene activity related to sleep, metabolism, and other bodily functions. Found in many organisms, including humans, CRY proteins act as molecular timekeepers, ensuring that various biological processes occur at appropriate times during the 24-hour day.
