MRAS
MRAS全稱為肌肉RAS癌基因同源物（Muscle RAS oncogene homolog），屬于RAS超家族成員，也被稱為RAS樣蛋白12（RASL12）。這類蛋白作為細胞內信號轉導的"分子開關"，通過結合GTP或GDP狀態調控下游通路，尤其在胚胎發育、細胞周期調控中扮演關鍵角色。MRAS異常激活與多種實體瘤密切相關，例如非小細胞肺癌中檢測到該基因的特異性突變位點，可能通過干擾細胞分化程序促進腫瘤進展。MRAS在心臟肥大反應和神經發育障礙中也顯示出調控作用，其表達異常與努南綜合征等遺傳性疾病存在關聯。
針對MRAS靶點的藥物開發長期受限于其蛋白結構的特殊性，傳統小分子抑制劑難以有效結合。但隨著KRAS G12C變構抑制劑的成功，研究者開始探索針對MRAS特有突變（如G23V）的共價結合策略。目前已有數款候選化合物進入臨床前研究階段，通過模擬天然蛋白構象或阻斷效應蛋白結合域來干預信號傳導。MRAS與SHOC2-PP1C復合物的特異性相互作用為開發精準療法提供了新方向，相關研究成果已進入轉化醫學驗證階段。
