美迪西请解决为您解讲怎样的是KRAS？

RAS是GTPase原癌表观遗传一家会员，比如3个频繁相关内容的RAS亚型，HRAS,KRAS and NRAS。RAS is a family of GTPase proto-oncogenes, comprising three closely related RAS isoforms:HRAS,KRAS and NRAS.在很多RAS亚型中，KRAS基因突变性频带宽度最大，KRAS基因突变性比较普遍于胰腺癌，肺肿瘤和结结肠癌。KRAS gene is a proto-oncogene that encodes a GTP/GDP-binding protein, that belongs to the GTPase RAS family.KRAS什么是基因遗传是代码GTP/GDP运用实际球淀粉酶质的原癌什么是基因遗传，专属GTPase RAS氏族。KRAS球淀粉酶质看做团伙旋转开关，在GDP运用实际的无几丁质酶的情况和GTP运用实际的几丁质酶的情况间无限循环。KRAS球淀粉酶质对应顺利通过与GTP和GDP运用实际，在无几丁质酶团伙和几丁质酶行驶间转型。The KRAS protein acts as molecular switches that cycle between a GDP-bound inactive state and a GTP-bound active state. KRAS protein switches between an inactive to an active form via binding to GTP and GDP respectively。
