This is the corresponding normal cellular gene to an oncogene that is responsible for normal cell growth and division.

PROTO-ONCOGENES are corresponding normal cellular genes to an oncogene that is responsible for normal cell growth and division.
An oncogene refers to a gene that is capable of causing cancer due to damage to the DNA molecule either by virus or other DNA damaging agents. A proto oncogene is the normal version of the gene while an oncogene is the abnormal version of the concerned gene.

A gene that code for proteins and responsible for normal cell growth and division is called proto-oncogenes. Mutations in proto-oncogenes can lead to an increase in protein expression or produce too many copies of it and become oncogene that can contribute to cancer cells. Furthermore, proto-oncogenes have many various roles in the cell. Some of them provide signals that lead to cell division and others regulate programmed cell death.
