HSP90AB1是热休克蛋白90(HSP90)家族的一员,属于HSP90β亚型。HSP90家族是一类高度保守的分子伴侣蛋白,主要功能是协助蛋白质的正确折叠、稳定和激活,尤其在细胞应激条件下发挥关键作用。HSP90AB1广泛表达于各种组织,主要位于细胞质,但也可能存在于细胞膜或分泌到细胞外。它通过与客户蛋白(如激酶、转录因子和激素受体)结合,维持它们的构象和功能稳定性。HSP90AB1在多种细胞过程中起重要作用,包括信号转导、细胞周期调控、凋亡抑制和免疫应答。突变或异常表达可能影响其功能,导致蛋白质错误折叠或降解,进而引发疾病。HSP90AB1的过表达常见于多种癌症,如乳腺癌、肺癌和前列腺癌,与肿瘤细胞的增殖、侵袭和耐药性密切相关。过表达可能通过稳定致癌蛋白(如HER2、AKT和突变型p53)促进肿瘤发展。相反,降低HSP90AB1表达可能影响正常细胞的应激反应和蛋白质稳态,导致细胞功能紊乱或凋亡。HSP90AB1抑制剂(如17-AAG和格尔德霉素)已被开发为抗癌药物,通过阻断其功能诱导客户蛋白降解。HSP90家族包括HSP90α(诱导型)和HSP90β(组成型)等成员,它们共享高度相似的序列和结构,但表达模式和调控机制不同。HSP90家族蛋白均具有ATP酶活性,依赖ATP循环完成客户蛋白的折叠和成熟。HSP90AB1在炎症、神经退行性疾病和感染中也发挥作用,其表达水平可能作为某些疾病的生物标志物或治疗靶点。
This gene encodes a member of the heat shock protein 90 family; these proteins are involved in signal transduction, protein folding and degradation and morphological evolution. This gene encodes the constitutive form of the cytosolic 90 kDa heat-shock protein and is thought to play a role in gastric apoptosis and inflammation. Alternative splicing results in multiple transcript variants. Pseudogenes have been identified on multiple chromosomes. [provided by RefSeq, Dec 2012]
