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 mouse TL1A protein has a transmembrane domain (40-60 a.a.) that can be cleaved into membrane-type and soluble peptide fragments. TL1A/TNFSF15 Protein, Mouse is the extracullar part of TL1A protein (I76-L252), produced in E.coli with tag free.
