Src (proto-oncogene)

Src is a gene that produces a protein functioning as a proto-oncogene, meaning it normally helps regulate cell growth and division. When Src works correctly, it contributes to healthy cellular processes. However, mutations or abnormal activation of Src can cause it to promote excessive or uncontrolled cell growth, which may lead to cancer. Essentially, Src plays a key role in signaling pathways that control how cells grow and divide, and its malfunction can disrupt this balance, potentially contributing to tumor formation.
