PTPN22

PTPN22,即蛋白酪氨酸磷酸酶非受體22型。別名PEST-Domain Phosphatase、PTPN8、PEP。PTPN22基因位于1號染色體上,表達(dá)產(chǎn)物為Protein Tyrosine Phosphatase Non-Receptor Type 22。PTPN22是一種淋巴細(xì)胞特異性的細(xì)胞內(nèi)磷酸酶,與分子適配器蛋白CBL相關(guān),可能參與調(diào)節(jié)T細(xì)胞受體信號通路中的CBL功能。該基因的突變與多種自身免疫性疾病有關(guān),如1型糖尿病、類風(fēng)濕關(guān)節(jié)炎、系統(tǒng)性紅斑狼瘡和Graves病。PTPN22在調(diào)節(jié)T細(xì)胞信號傳導(dǎo)中起關(guān)鍵作用,通過去磷酸化T細(xì)胞信號通路中的關(guān)鍵激酶如Lck、ZAP70、Vav和EB1來抑制T細(xì)胞抗原受體(TCR)信號傳導(dǎo)。此外,PTPN22還在血小板功能和動脈血栓形成中發(fā)揮負(fù)調(diào)控作用,PTPN22缺乏會顯著縮短尾部出血時間并加速動脈血栓形成,而不會影響靜脈血栓形成和凝血因子VIII和IX。
