分子別名(Synonym)
IL-15 R alpha,CD215,IL15RA,IL-15RA,IL-15R-alpha
表達區(qū)間及表達系統(tǒng)(Source)
Human IL-15 R alpha, Fc Tag (ILA-H5253) is expressed from human 293 cells (HEK293). It contains AA Ile 31 - Thr 205 (Accession # Q13261-1).
Predicted N-terminus: Ile 31
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 44.8 kDa. The protein migrates as 58-66 kDa 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)
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
IL15R是IL15RA、IL2RB和IL2RG的異三聚體。IL-15RA,也稱為CD215、IL-15Rα,是一種廣泛表達的60kDa跨膜糖蛋白。白細(xì)胞介素-15的高親和力受體。可以順式和反式信號,其中來自一個細(xì)胞亞群的IL15R將IL15呈遞給相鄰的IL2RG表達細(xì)胞。不同異構(gòu)體的表達可能會改變或干擾信號轉(zhuǎn)導(dǎo)。白細(xì)胞介素(IL)-15超激動劑/IL-15受體α融合復(fù)合物(IL-15SA/IL-15RA;ALT-803)激活CD8 T細(xì)胞和NK細(xì)胞上的IL-15受體,并顯示出顯著的抗腫瘤作用。信號轉(zhuǎn)導(dǎo)涉及SYK。與膜結(jié)合形式相比,可溶性sIL-15RA形式在所有腦結(jié)構(gòu)中都存在更高水平。
