βII spectrin, the most common isoform of non-erythrocyte spectrin, is a cytoskeleton protein present in all nucleated cells. Interestingly, βII spectrin is essential for the development of various organs such as nerve, epithelium, inner ear, liver and heart. The functions of βII spectrin include not only establishing and maintaining the cell structure but also regulating a variety of cellular functions, such as cell apoptosis, cell adhesion, cell spreading and cell cycle regulation. Notably, βII spectrin dysfunction is associated with embryonic lethality and the DNA damage response. More recently, the detection of altered βII spectrin expression in tumors indicated that βII spectrin might be involved in the development and progression of cancer. Its mutations and disorders could result in developmental disabilities and various diseases. The versatile roles of βII spectrin in disease have been examined in an increasing number of studies; nonetheless, the exact mechanisms of βII spectrin are still poorly understood. Thus, we summarize the structural features and biological roles of βII spectrin and discuss its molecular mechanisms and functions in development, homeostasis, regeneration and differentiation. This review highlight the potential effects of βII spectrin dysfunction in cancer and other diseases, outstanding questions for the future investigation of therapeutic targets. The investigation of the regulatory mechanism of βII spectrin signal inactivation and recovery may bring hope for future therapy of related diseases.

βII 血影蛋白 (SPTBN1):在癌症和其他疾病中的生物学功能和临床潜力

βII 血影蛋白是非红细胞血影蛋白最常见的同种型,是存在于所有有核细胞中的细胞骨架蛋白。有趣的是,βII 血影蛋白对神经、上皮、内耳、肝脏和心脏等各种器官的发育至关重要。βII Spectrin 的功能不仅包括建立和维持细胞结构,还包括调节多种细胞功能,如细胞凋亡、细胞粘附、细胞扩散和细胞周期调节。值得注意的是,βII 血影蛋白功能障碍与胚胎致死率和 DNA 损伤反应有关。最近,检测到肿瘤中 βII 血影蛋白表达的改变表明 βII 血影蛋白可能参与了癌症的发展和进展。它的突变和紊乱可能导致发育障碍和各种疾病。βII 血影蛋白在疾病中的多种作用已在越来越多的研究中得到检验。尽管如此,βII 血影蛋白的确切机制仍知之甚少。因此,我们总结了 βII 血影蛋白的结构特征和生物学作用,并讨论了其在发育、稳态、再生和分化中的分子机制和功能。这篇综述强调了 βII 血影蛋白功能障碍在癌症和其他疾病中的潜在影响,这是未来研究治疗靶点的悬而未决的问题。对βII Spectrin信号失活和恢复调控机制的研究可能为未来相关疾病的治疗带来希望。βII 血影蛋白的确切机制仍然知之甚少。因此,我们总结了 βII 血影蛋白的结构特征和生物学作用,并讨论了其在发育、稳态、再生和分化中的分子机制和功能。这篇综述强调了 βII 血影蛋白功能障碍在癌症和其他疾病中的潜在影响,这是未来研究治疗靶点的悬而未决的问题。对βII Spectrin信号失活和恢复调控机制的研究可能为未来相关疾病的治疗带来希望。βII 血影蛋白的确切机制仍然知之甚少。因此,我们总结了 βII 血影蛋白的结构特征和生物学作用,并讨论了其在发育、稳态、再生和分化中的分子机制和功能。这篇综述强调了 βII 血影蛋白功能障碍在癌症和其他疾病中的潜在影响,这是未来研究治疗靶点的悬而未决的问题。对βII Spectrin信号失活和恢复调控机制的研究可能为未来相关疾病的治疗带来希望。这篇综述强调了 βII 血影蛋白功能障碍在癌症和其他疾病中的潜在影响,这是未来研究治疗靶点的悬而未决的问题。对βII Spectrin信号失活和恢复调控机制的研究可能为未来相关疾病的治疗带来希望。这篇综述强调了 βII 血影蛋白功能障碍在癌症和其他疾病中的潜在影响,这是未来研究治疗靶点的悬而未决的问题。对βII Spectrin信号失活和恢复调控机制的研究可能为未来相关疾病的治疗带来希望。
