TPR domain assigns versatility of BcTir/Tpr system against viral infection

NAD+-derived signal produced by TIR domain triggered the host immune responses. The ubiquitous TPR domain involved in signal recognition and effector activation were found widely assembled with the TIR domain. However, the immune roles of these assemblies remain elusive. Here, a two-gene operon, one containing a TIR domain, designated as BcTir, and the other, BcTpr, from Bacillus cereus,…
