The TL1A protein (VEGI protein), belongs to the tumor necrosis factor (TNF) family and is a receptor for TNFRSF25 and TNFRSF6B. TL1A is involved in the activation of NF-κB and C-Jun pathways, which can be used as a regulator of mucosal immunity and participate in the immune pathway of inflammatory bowel disease (IBD) pathogenesis [1] [2] . TL1A originates from endothelial cells and inhibits the proliferation of breast cancer, epithelial and myeloid tumor cells [3] . The human TL1A protein has a transmembrane domain (36-56 a.a.) that can be cleaved into membrane-type and soluble peptide fragments. Animal-Free TL1A/TNFSF15 Protein, Human (His) is the extracullar part of TL1A protein (Q58-L251), produced in E.coli with C-terminal His-tag.This product is for cell culture use only.

Human

TL1A (Tumor necrosis factor-like cytokine 1A), also known as TNF ligand-related molecule 1 and vascular endothelial cell growth inhibitor (VEGI), is the receptor for TNFRSF25 and TNFRSF6B, acts as a regulator of mucosal immunity and participates in immunological pathways involved in the inflammatory bowel diseases (IBD) pathogenesis [1] . TL1A belongs to the tumor necrosis factor family, derived from endothelial cell. It is a ligand for DR3 and decoy receptor TR6/DcR3, the interaction with DR3 promotes T cell expansion during an immune response, whereas TR6 has an opposing effect. Moreover, DR3 is the death domain-containing receptor, that is upregulated during T cell activation. TL1A shows an inducible expression by TNF and IL-1alpha, and induces NF-kappaB activation and apoptosis in DR3-expressing cell lines. Meanwhile, TL1A acts as a costimulator that increases IL-2 responsiveness and secretion of proinflammatory cytokines [2] . In addition, TL1A activates c-Jun N-terminal kinase. TL1A also activates caspase-3 leading to PARP cleavage, and inhibits the proliferation of breast carcinoma, epithelial, and myeloid tumor cells. TL1A promotes proliferation of normal human fibroblast cells. These results suggest that VEGI, a new member of the TNF family, has a signaling pathway similar to TNF and is most likely a multifunctional cytokine [3] . Human TL1A protein has two glycosylated domains and one transmembrane domain (36-56 a.a.), and can be cleaved into membrane-type peptide fragments and soluble peptide fragments. The protein sequence of human is much different from mouse and rat with similarities of 68.42% and 70.45%, respectively.
