Abstract: BANK1, an adaptor protein expressed in B-cells, plays a little understood role in B-cell signaling. Because BANK1 contains an N-terminal putative Toll-interleukin 1 receptor (TIR) domain, we used mouse Bank1−/− splenic B cells to test if BANK1 affects signaling induced by the TLR9 agonist CpG. Following CpG stimulation BANK1 deficiency reduced p38 phosphorylation without affecting that of ERK or JNK and reduced IL-6 secretion. Bank1−/− B cells showed reduced phosphorylation of MNK1/2 and eIF4E, suggesting an …
