TLN1(Talin-1)是一种编码细胞骨架连接蛋白的基因,属于Talin基因家族(包括TLN1和TLN2),其家族成员在细胞黏附、迁移和信号传导中起核心作用。TLN1的主要功能是通过连接整合素(细胞膜上的黏附受体)与肌动蛋白细胞骨架,调控细胞与细胞外基质的相互作用,从而影响细胞形态、运动和机械力感知。其表达产物Talin-1蛋白包含头部结构域(与整合素结合)和杆状结构域(与肌动蛋白结合),并通过自身构象变化激活整合素信号通路。TLN1的作用位点集中在黏着斑(focal adhesion),即细胞与基质接触的动态结构。TLN1突变可能导致功能丧失,引发整合素激活障碍,表现为细胞迁移缺陷、组织发育异常或免疫功能障碍。例如,TLN1突变与某些遗传性血小板减少症和免疫缺陷疾病相关,因其影响血小板的聚集和淋巴细胞的迁移。TLN1过表达可能增强细胞黏附与迁移能力,促进肿瘤转移,而低表达则导致细胞黏附松散,影响伤口愈合或胚胎发育。在癌症中,TLN1的异常表达常与侵袭性表型相关。Talin基因家族的共性包括:均含有FERM结构域(介导蛋白相互作用)、机械敏感序列,并能响应力学信号调控细胞行为。TLN1还参与Wnt/β-catenin等信号通路的交叉调控,其表达水平变化可能间接影响其他黏附相关基因(如FAK、Vinculin)的功能。
This gene encodes a cytoskeletal protein that is concentrated in areas of cell-substratum and cell-cell contacts. The encoded protein plays a significant role in the assembly of actin filaments and in spreading and migration of various cell types, including fibroblasts and osteoclasts. It codistributes with integrins in the cell surface membrane in order to assist in the attachment of adherent cells to extracellular matrices and of lymphocytes to other cells. The N-terminus of this protein contains elements for localization to cell-extracellular matrix junctions. The C-terminus contains binding sites for proteins such as beta-1-integrin, actin, and vinculin. [provided by RefSeq, Feb 2009]
