Cyclins
Cyclins are proteins that play a crucial role in regulating the cell cycle, which is the process by which cells grow and divide. They help control when a cell moves from one phase of the cycle to the next by activating enzymes called cyclin-dependent kinases (CDKs). As cells prepare to divide, the levels of cyclins rise and fall, ensuring that each stage of the cell cycle occurs in the correct order and at the right time. This process is vital for proper cell function and growth, and errors in cyclin regulation can lead to diseases like cancer.

Cyclins are a group of proteins that play a crucial role in regulating the cell cycle, the series of events leading to cell division and replication. Their levels fluctuate throughout the cell cycle, rising and falling at specific times to activate enzymes called cyclin-dependent kinases (CDKs). Together, cyclins and CDKs ensure that cells progress through the different phases of division at the right time and in the correct sequence. This regulation is vital for proper cell division, growth, and maintenance of healthy tissue, as errors can lead to issues like cancer.
