TGFBR2(转化生长因子β受体2,Transforming Growth Factor Beta Receptor 2)是一种跨膜蛋白受体,属于TGF-β受体家族。该基因编码的蛋白质是TGF-β信号通路的关键组成部分,通过与TGF-β配体结合并和TGFBR1形成复合物,激活下游的SMAD蛋白(一类参与信号转导的蛋白质),进而调控细胞增殖、分化、凋亡、迁移及细胞外基质合成等生物学过程。TGFBR2的主要作用位点是细胞膜,其功能异常会影响多种组织的稳态,尤其在胚胎发育、免疫调节和伤口愈合中起重要作用。TGFBR2的突变可能导致功能丧失,与多种疾病相关,例如马凡综合征(一种结缔组织疾病)、Loeys-Dietz综合征(一种血管和结缔组织异常疾病)以及多种癌症(如结直肠癌、胃癌)。在癌症中,TGFBR2的突变或表达降低可能导致TGF-β信号通路抑制,从而促进肿瘤细胞的增殖和转移。相反,在某些纤维化疾病中,TGFBR2的过表达可能加剧纤维化进程,因其过度激活会促进细胞外基质的过度沉积。TGFBR2属于TGF-β受体家族,该家族成员均具有丝氨酸/苏氨酸激酶活性(一种能够磷酸化其他蛋白质的酶活性),并通过类似的机制传递信号。基因家族的共性包括参与细胞生长和分化的调控,并在发育和疾病中发挥多重作用。TGFBR2的表达水平变化可能影响其他基因的表达,例如下调可能减少SMAD蛋白的激活,从而影响下游靶基因(如细胞周期调控基因)的表达;而过表达可能增强TGF-β信号,导致过度纤维化或免疫抑制。该基因的异常表达或突变对机体的影响复杂,可能因组织类型和疾病背景而异。
This gene encodes a member of the Ser/Thr protein kinase family and the TGFB receptor subfamily. The encoded protein is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with another receptor protein, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of a subset of genes related to cell proliferation. Mutations in this gene have been associated with Marfan Syndrome, Loeys-Deitz Aortic Aneurysm Syndrome, and the development of various types of tumors. Alternatively spliced transcript variants encoding different isoforms have been characterized. [provided by RefSeq, Jul 2008]
该基因编码的丝氨酸/苏氨酸蛋白激酶家族和TGFB受体亚家族的一个成员。所编码的蛋白质是具有蛋白激酶结构域,形成与另一受体蛋白质的异二聚体复合物,并结合的TGF-β的跨膜蛋白。该受体/配体复合物磷酸化的蛋白质,然后进入细胞核,并调节与细胞增殖的基因的一个子集的转录。在这个基因的突变已与马凡综合征,Loeys-德茨主动脉瘤综合征,以及各种类型的肿瘤的发展有关。编码不同同种型的可变剪接转录物变体已被表征。 [由RefSeq的,2008年7月提供]
