Tumor-suppressor genes generally encode proteins that in one way or another inhibit cell proliferation. Loss-of-function mutations in one or more of these proliferation inhibitory proteins contribute to the development of many cancers. Prominent among the classes of proteins encoded by tumor-suppressor genes are:

A. Intracellular proteins that regulate or inhibit entry into the cell cycle

B. Receptors or signal transducers for secreted hormones or developmental signals that inhibit cell proliferation

C. Checkpoint pathway proteins that arrest the cell cycle if DNA is damaged

D. Proteins that promote apoptosis

Following genes belongs to the above class-

i. p53

ii. Rb

iii.TGF- β

iv. Caspase 3 and 7
