Mouse GUCY2C / Guanylyl cyclase C Protein, His Tag (MALS verified)

分子別名（Synonym）

GUCY2C,GUC2C,STAR,STA receptor,hSTAR,GC-C

表達(dá)區(qū)間及表達(dá)系統(tǒng)（Source）

Mouse GUCY2C, His Tag (GUC-M52H3) is expressed from human 293 cells (HEK293). It contains AA Val 20 - Met 433 (Accession # Q3UWA6-1).

Predicted N-terminus: Val 20

蛋白結(jié)構(gòu)（Molecular Characterization）

This protein carries a polyhistidine tag at the C-terminus

The protein has a calculated MW of 49.0 kDa. The protein migrates as 65-95 kD when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

內(nèi)毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

純度（Purity）

>90% as determined by SDS-PAGE.

制劑（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景（Background）

GUCY2C（鳥苷酸環(huán)化酶C），也稱為熱穩(wěn)定腸毒素受體，是鳥苷酸環(huán)合酶（gc）家族的I型跨膜蛋白，通過產(chǎn)生cGMP發(fā)出信號。鳥苷酸環(huán)化酶C（GUCY2C）及其激素鳥苷酸和尿鳥苷酸最近成為一個(gè)旁分泌軸，保護(hù)腸粘膜完整性免受突變、化學(xué)和炎癥損傷。GUCY2C小鼠CAR-T細(xì)胞識別并殺死內(nèi)源性表達(dá)GUCY2C的人結(jié)直腸癌癌癥細(xì)胞。因此，我們已經(jīng)確定了一種人類GUCY2C-特異性CAR-T細(xì)胞治療方法，該方法可能被開發(fā)用于治療GUCY2C外轉(zhuǎn)移性癌癥。
