CDK4

CDK4，即細胞周期蛋白依賴性激酶4，別名P15INK4B結合伴侶、P16INK4A結合伴侶、CDKN2A/p16INK4a互作伴侶等。它是一種由CDK4基因編碼的絲氨酸/蘇氨酸激酶，屬于細胞周期調控蛋白家族成員。CDK4在細胞周期的G1期向S期轉換中發揮關鍵作用，主要通過與周期蛋白D（cyclin D）形成復合體，磷酸化視網膜母細胞瘤蛋白（Rb），從而促進Rb蛋白的去磷酸化，釋放E2F家族轉錄因子，推動細胞周期進程。CDK4在生物學上的意義非常廣泛，它參與調控細胞周期、細胞增殖、分化和衰老等重要生物學過程。CDK4的活性受到多種因素的精細調控，包括周期蛋白的合成、降解以及CDK抑制因子（CKIs）的抑制作用。CDK4的功能異常與多種疾病有關，尤其是與腫瘤的發生發展密切相關。例如，在多種腫瘤中觀察到CDK4的過表達或Rb蛋白功能喪失，導致細胞周期失控和腫瘤細胞的無限制增殖。因此，CDK4是腫瘤治療中的一個潛在靶點，針對CDK4的小分子抑制劑正在被開發用于治療某些類型的癌癥。
