Encoded as NRAS gene in humans with a nearby genes order of cenCD2NGFBNRAStel, Neuroblastoma RAS viral oncogene homolog is an enzyme discovered at the Institute of Cancer Research in London in which harvey and kirsten ras genes (HRASandKRAS) comprises its mammalian ras gene family.
NRAS is an enzyme that in humans is encoded by the NRAS gene. The order of nearby genes is as follows: cenCD2NGFBNRAStel. It was discovered by a small team of researchers led by Robin Weiss at the Institute of Cancer Research in London. The mammalian ras gene family consists of the harvey and kirsten ras genes (HRAS and KRAS), an inactive pseudogene of each (c-Hras2 and c-Kras1) and the N-ras gene.
