Oncoprotein

Part of speech: noun

Definitions

1. A specific class of proteins encoded by oncogenes that play a significant role in cell division and survival, often contributing to tumor formation and cancer metastasis
2. A group of proteins generated from oncogenes, crucial in regulating cellular activities like growth and survival, which are frequently associated with cancerous transformations
3. A type of protein produced by genes linked to cancer that influences cellular processes such as growth and survival, often implicated in tumor development and progression

Etymology: The word is a modern scientific compound built from two pieces: "onco-", from the Ancient Greek "ónkos", meaning "mass" or "swelling" (the root behind the Greek sense of a tumour), and "protein". The Greek element reached English through New Latin "onco-", a combining form used in medical and biological coinages, so the ancient word itself never referred to a protein or to a gene. "Protein" is itself a 19th-century coinage, named from the Greek "prōteios", meaning "primary" or "of first importance". Joining the two, "oncoprotein" describes proteins that are made from oncogenes and that drive cell division and survival, which is why a term built from "swelling" and "primary" now names a family of molecules central to cancer research.
