PATHOLOGY

Detailed explanation-1: -Of the many proteins involved in cell cycle control, cyclin-dependent kinases (CDKs) are among the most important. CDKs are a family of multifunctional enzymes that can modify various protein substrates involved in cell cycle progression.

Detailed explanation-2: -Cyclins control cell cycle progression by regulating the activity of cyclin-dependent kinases (Cdks). Cyclin I is a member of the cyclin family because of the presence of a cyclin box motif.

Detailed explanation-3: -Cyclins regulate the timing of the cell cycle in eukaryotic cells.

Detailed explanation-4: -Abstract. Cyclin A is a pivotal regulatory protein which, in mammalian cells, is involved in the S phase of the cell cycle. Transcription of the human cyclin A gene is cell cycle regulated.
