Cyclin p53
Webp53: cell cycle regulatory protein that regulates cell growth and monitors DNA damage; it halts the progression of the cell cycle in cases of DNA damage and may induce … WebCyclin is responsible for inhibiting retinoblastoma proteins. P53, another protein involved in cell cycle regulations, can be highly mutagenized---which results in its presence in many cancer types. One of its jobs is to monitor cell damage---being DNA damage or mitochondrial damage.
