The set of genes used to regulate the cell cycle are called cyclins.

Cyclins are a family of proteins that play a crucial role in controlling the progression of cells through the cell cycle. They do this by activating cyclin-dependent kinases (CDKs), which are essential for the transition between different phases of the cell cycle. The levels of cyclins fluctuate throughout the cycle, which helps regulate cell division and ensure proper cellular function.

While proto-oncogenes and kinases also play roles in cellular regulation and signaling, the specific term for the set of genes directly regulating the cell cycle is indeed cyclins.
