Generally two types of genes are present for the regulation of cell division. They are proto oncogenes and Tumour suppressor genes.
Regulation of cell cycle involves the steps that promote or inhibit the cell cycle.
Proto oncogenes are the genes that code for cyclins that promote cell division. Whereas, Tumour suppressor genes are the genes that code for cyclins that inhibit cell division. Cyclins are the regulatory proteins of cell cycle.
Without this regulation, causes the cancer due to uncontrolled cell division. So, mutations in these genes causes cancer.
Thus, proto oncogenes promotes cell division and Tumour suppressor genes inhibit cell division.
