Cyclin E1 is a protein that plays a crucial role in the regulation of the cell cycle, particularly during the G1 phase. It is a member of the cyclin family, which are proteins that bind to and activate cyclin-dependent kinases (CDKs). The cyclin E1-CDK2 complex is essential for the progression of cells from the G1 phase to the S phase, where DNA replication occurs.
In cancer, cyclin E1 has been found to be overexpressed in various types of tumors, including breast, ovarian, and lung cancers. This overexpression can lead to uncontrolled cell proliferation, a hallmark of cancer.
