YOD1 activates RIPK2. 4 / 4
| 4

reach
"Indeed, we found that, after blocking protein synthesis with CHX, YOD1 deletion accelerated the degradation of RIPK2 in BMDMs in the presence or absence of L18-MDP (Fig. 5G; Appendix Fig. S12A), indicating that YOD1 increases the stability of RIPK2 protein."

reach
"Consistently, YOD1 overexpression increased RIPK2 protein abundance and delayed RIPK2 degradation upon CHX treatment (Appendix Fig. S12B)."

reach
"Since RIPK2 is essential for NOD2 signaling and YOD1 stabilizes RIPK2, overexpression of YOD1 strongly increased L18-MDP-induced NF-κB and MAPK activation as well as cytokine production (Appendix Fig. S13)."

reach
"Altogether, these findings show that YOD1 enhances NOD2 signaling in macrophages by stabilizing RIPK2."
