Description
General description
Research area: Apoptosis
Cyclin dependent kinase 1 (CDK1), a type of serine/threonine kinase, is a catalytic subunit of the M phase-promoting factor (MPF) complex.
Biochem/physiol Actions
Cyclin B protein regulates mitosis in all eukaryotes. Cyclin B binds to cyclin dependent kinase 1 (CDK1), forming a complex that triggers the start of mitosis by phosphorylating specific proteins. Cyclin B regulates the activation, subcellular localization, and target selection of CDK1. Its destruction is essential for the completion of mitosis. Overexpression of human cyclin B1 has been linked to aggressive tumor behavior and is frequently observed in various cancers.
CDK1 plays a key role in driving the M-phase in both meiosis and mitosis. It becomes highly active at the start of the M-phase and becomes inactive at the end. CDK1 controls various important events in the cell, such as DNA replication, segregation, and repair, as well as mRNA transcription and cell morphogenesis. Additionally, it regulates ribosome assembly by targeting specific ribosomal proteins.
