Human TL1A / TNFSF15 Protein, Fc Tag, active trimer (MALS verified)

分子别名(Synonym)

TL1A, VEGI, TNFSF15

表达区间及表达系统(Source)

Human TL1A Protein, Fc Tag (TLA-H5263) is expressed from human 293 cells (HEK293). It contains AA Val 84 - Leu 251 (Accession # O95150-1).

Predicted N-terminus: Pro

蛋白结构(Molecular Characterization)

This protein carries a human IgG1 Fc tag at the N-terminus.

The protein has a calculated MW of 85.1 kDa. The protein migrates as 95-110 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

背景(Background)

TNF-like cytokine 1A (TL1A) and its receptors, death receptor 3 (DR3) and decoy receptor 3 (DcR3) are members of the TNF and TNF receptor superfamilies of proteins, respectively. Binding of APC-derived TL1A to lymphocytic DR3 provides co-stimulatory signals for activated lymphocytes. DR3 signaling affects not only the proliferative activity of and cytokine production by effector lymphocytes, but also critically influences the development and suppressive function of regulatory T-cells. Whereas, DcR3 restricts the function of the TL1A/DR3 complex: attenuating T-cell activation and downregulating the secretion of pro-inflammatory cytokines. Together with DR3 and DcR3, TL1A constitutes a cytokine system that actively interferes with the regulation of immune responses.
