KRAS - Wikipedia
KRAS (Kirsten rat sarcoma virus) is a gene that provides instructions for making a protein called K-Ras, a part of the RAS/MAPK pathway. The protein relays signals from outside the cell to the cell's nucleus. These signals instruct the cell to grow and divide (proliferate) or to mature and take on specialized functions (differentiate).
KRAS靶点的前世今生 - 知乎 - 知乎专栏
KRAS基因的全名叫Kirstenratsarcomaviraloncogenehomolog,翻成中文是“Kirsten大鼠肉瘤病毒癌基因同源物”。 KARS基因编码的蛋白是一种小GTP酶(smallGTPase),它属于RAS超蛋白家族。 在人的基因组中,有2个KRAS基因。 一个是KRAS1,位于第6号染色体的短臂上;另一个是KRAS2,位于第12号染色体的短臂上。 其中, KRAS1是“假基因”,不能被转录成RNA,所以它是没有功能的。 而KRAS2才是“真基因”,能够转录、并且翻译成蛋白,具有生物学活性。 …

KRAS: From undruggable to a druggable Cancer Target
RAS exists in three different isoforms (K-RAS, H-RAS and N-RAS) with high sequence homology. K-RAS is the most commonly mutated RAS isoform. The Ras protein is a membrane bound protein with inherent GTPase activity and is activated by numerous extracellular stimuli, cycling between an inactive (GDP-bound) and active (GTP-bound) form.
