CCR2/Gα16/HEK293
CBP71055
I. Background | |
CCR2(C-C 趨化因子受體 2 型)是表達(dá)于單核細(xì)胞、巨噬細(xì)胞等免疫細(xì)胞表面的 G 蛋 白偶聯(lián)受體(GPCR),具有七次跨膜螺旋結(jié)構(gòu),胞外 N 端含有糖基化位點(diǎn),胞內(nèi) C 端則 負(fù)責(zé)信號(hào)轉(zhuǎn)導(dǎo)的蛋白相互作用域。人 CCR2 蛋白由 374 個(gè)氨基酸構(gòu)成,具有兩個(gè)主要剪接 變體:CCR2A 和 CCR2B,其中 CCR2B 是最常見(jiàn)的功能型形式。 |
|
II. Description | |
CCR2 與配體結(jié)合,導(dǎo)致 Gαq 亞基的激活,觸發(fā) PLC-γ,從而產(chǎn)生兩個(gè)第二信使:IP3 和 DAG,它們參與細(xì)胞內(nèi)鈣動(dòng)員。
