表型提示
MGI:2442572Mice homozygous for a knock-out allele exhibit increased susceptibility to bacterial infection and altered TLR9-activated inflammatory responses. Mice homozygous for a different knock-out allele exhibit mislocalization of opsin, increased apoptosis and proliferation of photoreceptors in the inner nuclear layer and disrupted localization of amacrine cells.
STK38,全称为丝氨酸/苏氨酸激酶38,是NDR(Never in Mitosis Gene A Related Kinase)/LATS(Large Tumor Suppressor)激酶家族的成员之一。NDR/LATS激酶家族在细胞周期调控、细胞凋亡、细胞迁移和炎症反应等生物学过程中发挥着重要作用。STK38主要在细胞质中表达,其功能涉及到细胞骨架的组装、细胞粘附、细胞信号转导以及细胞代谢等方面。

STK38在多种疾病的发生发展中发挥着重要作用,例如结直肠癌、乳腺癌、胰腺癌和脂肪肝等。在结直肠癌中,STK38与NLRP12蛋白相互作用,通过抑制GSK3β的磷酸化,进而抑制Wnt/β-catenin信号通路的激活,从而抑制肿瘤的发生发展[1]。在乳腺癌中,circCAPG编码的CAPG-171aa蛋白通过破坏STK38与SMAD-specific E3 ubiquitin protein ligase 1 (SMURF1)的结合,从而抑制MEKK2的泛素化降解,激活MEKK2-MEK1/2-ERK1/2信号通路,促进肿瘤的生长和转移[2]。在胰腺癌中,Caprin-1蛋白与STK38和ULK1相互作用,通过调节ULK1的磷酸化水平,激活自噬,从而促进肿瘤的生长[6]。在脂肪肝中,高脂肪饮食诱导的STK38表达上调,通过促进NF-κB的核转位和脂质生成,导致炎症和胰岛素抵抗[7]。

此外,STK38还与心脏发育和心脏功能密切相关。在心肌细胞中,STK38通过磷酸化RNA结合蛋白Rbm24,调节Rbm24的稳定性和功能,进而调节肌小节的组装和心脏收缩力[3]。在炎症反应中,STK38通过促进MEKK2的泛素化降解,抑制TLR9介导的炎症反应,从而保护宿主免受炎症损伤[4]。在细胞应激反应中,STK38的激活受到GSK-3β的调节,STK38的激活对于细胞抵抗氧化应激引起的细胞死亡至关重要[5]。在鱼类的免疫系统中,STK38通过与GSK3β相互作用,调节IFN I的表达,发挥抗病毒免疫作用[8]。

综上所述,STK38是一个功能复杂的激酶,参与调节多种生物学过程,包括细胞周期、细胞凋亡、细胞迁移、炎症反应、心脏发育和心脏功能等。STK38在多种疾病的发生发展中发挥重要作用,是一个潜在的药物靶点。未来,深入研究STK38的生物学功能和调控机制,对于开发新型药物和治疗方法具有重要意义。
