12p12.1

KRAS（Kirsten rat sarcoma viral oncogene homolog）是一种原癌基因，属于RAS基因家族，该家族还包括HRAS和NRAS。RAS家族基因编码小GTP酶蛋白，在细胞信号传导中起关键作用，主要调控细胞增殖、分化和存活。KRAS蛋白在RAS-MAPK和PI3K-AKT等信号通路中作为分子开关，通过结合GTP（激活状态）或GDP（失活状态）传递生长因子受体的信号。KRAS的常见突变（如G12D、G12V、G13D）会导致其持续激活，无法水解GTP，从而促进细胞不受控增殖，与多种癌症密切相关，尤其是胰腺癌（90%突变率）、结直肠癌（40%）和肺癌（30%）。KRAS突变还影响肿瘤微环境，促进免疫逃逸。KRAS过表达会增强下游通路活性，加速肿瘤进展和转移；而敲低KRAS可抑制肿瘤生长，但可能影响正常组织（如造血系统）的稳态。KRAS的突变体（如G12C）已成为靶向治疗热点，相关抑制剂（如Sotorasib）通过共价结合突变位点阻断信号传导。KRAS还与代谢重编程相关，突变后会增强糖酵解（Warburg效应）。KRAS家族基因的共性是编码高度保守的GTP结合蛋白，均含效应结构域和膜定位信号，依赖翻译后修饰（如法尼基化）定位至细胞膜。KRAS的不同剪接变体（4A/4B）可能影响其功能特异性。由于KRAS在癌症中的核心作用，其调控机制和靶向策略是肿瘤研究的重要方向。

This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants encoding two isoforms that differ in the C-terminal region. [provided by RefSeq, Jul 2008]

本基因，姬ras癌基因来自哺乳动物ras基因家族同源物，编码的蛋白质，它是小GTP酶超家族的成员。单一氨基酸取代是负责活化突变。该成果转化蛋白在各种恶性肿瘤，包括肺腺癌，粘液瘤，胰腺和结直肠癌性导管癌牵连。选择性剪接导致变体编码两种亚型，在C-末端区域不同。 [由RefSeq的，2008年7月提供]
