Considerable advances have recently been made in understanding the structure and function of the proteins encoded by the ras proto-oncogenes. In addition, a large number of ras-related small GTP-binding proteins with very diverse activities have now been identified. This review explores developments in this rapidly expanding field.

UI	MeSH Term	Description	Entries
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D015689	Oncogene Protein p21(ras)	Transforming protein encoded by ras oncogenes. Point mutations in the cellular ras gene (c-ras) can also result in a mutant p21 protein that can transform mammalian cells. Oncogene protein p21(ras) has been directly implicated in human neoplasms, perhaps accounting for as much as 15-20% of all human tumors. This enzyme was formerly listed as EC 3.6.1.47.	p21(v-Ha-ras),p21(v-Ki-ras),ras Oncogene Protein p21,p21 Transforming Viral Protein,p21 v-H-ras,p21 v-Ha-ras,p21 v-Ki-ras,p21 v-ras,p21(v-H-ras),p21(v-K-ras),ras Oncogene Product p21,ras Oncogene p21 Product,p21 v H ras,p21 v Ha ras,p21 v Ki ras,p21 v ras,v-H-ras, p21,v-Ha-ras, p21,v-Ki-ras, p21,v-ras, p21
D019204	GTP-Binding Proteins	Regulatory proteins that act as molecular switches. They control a wide range of biological processes including: receptor signaling, intracellular signal transduction pathways, and protein synthesis. Their activity is regulated by factors that control their ability to bind to and hydrolyze GTP to GDP. EC 3.6.1.-.
