The MAPK ERK is required for LPS-induced TNF production by macrophages. Although the scaffold kinase suppressor of Ras (KSR)1 is required for efficient Erk activation by mitogenic stimuli, the role of KSR1 in ERK activation by inflammatory and stress stimuli is unknown. In this study, we examined the effects of KSR deficiency on ERK activation by stress stimuli and show that ERK activation by TNF, IL-1, and sorbitol is attenuated in the absence of KSR1. To determine the significance of this defect in vivo, we tested KSR-deficient mice using a passive transfer model of arthritis. We found that the induction of arthritis is impaired in the absence of KSR. Thus, KSR plays a role in ERK activation during inflammatory and stress responses both in vitro and in vivo.
