表达区间及表达系统(Source)
Mouse CD40 Ligand Protein, His Tag (CDL-M5248) is expressed from human 293 cells (HEK293). It contains AA Gly 115 - Leu 260 (Accession # P27548-1).
Predicted N-terminus: His
蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 16.8 kDa. The protein migrates as 19-22 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

背景(Background)
CD40配体也称为CD40L、CD154、TNFSF5和T细胞抗原Gp39,是一种单程I型膜蛋白,属于TNF超家族分子。CD40配体主要在活化的CD4+T淋巴细胞上表达,也存在于其他类型的细胞中,包括血小板、肥大细胞、巨噬细胞、嗜碱性粒细胞、NK细胞、B淋巴细胞以及非造血细胞(平滑肌细胞、内皮细胞和上皮细胞)。尽管可溶性CD40配体的所有单体、二聚体和三聚体形式都可以与CD40结合,但三聚体形式的可溶性CD40配位体通过细胞表面CD40的寡聚化具有最强的生物活性,这是TNF受体家族成员的共同特征。
CD40配体与抗原呈递细胞(APC)上的CD40结合,这会根据靶细胞类型产生许多影响。一般来说,CD40配体起着共刺激分子的作用,与APC上MHC分子对T细胞受体的刺激相关,诱导APC的激活。CD40配体共有三个结合伴侣:CD40、α5β1整合素和αIIbβ3。CD40配体通过与B细胞表面的CD40结合来调节B细胞功能。该基因的缺陷导致无法进行免疫球蛋白类转换,并与高IgM综合征有关。
