WebAug 1, 2024 · For example, this paper reports the discovery of: a new cyclin, cyclin M, which appears to be most closely related to cyclin L. Its biological function is unknown, but it is related to cyclins that regulate transcription. It is now called cyclin L2. I hope this answer satisfies you to some extent. WebOveractive forms of these proteins are often found in cancer cells. For instance, oncogenic Ras mutations are found in about 90% of pancreatic cancers. Ras is a G protein, meaning that it switches back and forth between an inactive form (bound to the small molecule GDP) and an active form (bound to the similar molecule GTP).
