PG - 47-55 LID - S0378-1119(17)31035-1 [pii] LID - 10.1016/j.gene.2017.11.070 [doi] AB - Porcine butyrophilin-like 5 (Btnl5) is a novel member of the butyrophilin family, which consists of immune regulators. The expression pattern and the function of this gene remain unclear. In this study, Btnl5 is identified as a negative regulator of the NF-kappaB pathway. Our study indicates that Btnl5 is mainly expressed in intestinal epithelial cells (IECs) and expressed in membrane systems. Btnl5 inhibits MyD88-mediated activation of the NF-kappaB pathway. Btnl5 interacts with TNF receptor-associated factor 2 (TRAF2) and transcription factor p65. Besides, Btnl5 inhibits p65-mediated activation of the NF-kappaB pathway and inhibits nuclear translocation of p65. These results suggest that Btnl5 may inhibit NF-kappaB pathway through binding and interfere nuclear translocation of p65. CI - Copyright (c) 2017. Published by Elsevier B.V.
