proteína oncogénica p21 ras
Scope note: Proteína transformadora codificada por los oncogenes ras. Mutaciones puntuales en el gen ras celular (c-ras) también pueden dar por resultado una proteína p21 mutante que puede transformar células de mamíferos. La proteína oncogénica p21(ras) ha sido implicada directamente en neoplasias humanas, y posiblemente sea responsable del 15-20 por ciento de todos los tumores humanos. Esta enzima fue clasificada anteriormente como EC 3.6.1.47.

Scope note: 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.
