OTUB1 activates FGFR2. 6 / 6
| 6

reach
"Interestingly, OTUB1 inhibits FGFR2 degradation through lysosome, consistent with FGFR2 being a membrane protein."

reach
"OTUB1 promotes osteoblastic bone formation through stabilizing FGFR2."

reach
"Research indicates that E3 ubiquitin ligases are involved in regulating osteoblast differentiation and bone formation, such as OTUB1 promoting bone formation by stabilizing FGFR2, and Parkin inhibiting RANKL-induced osteoclastogenesis."

reach
"Finally, new research has discovered that OTUB1 enhances the activity of the FGFR2 signaling pathway by stabilizing FGFR2 and preventing its degradation."

reach
"In this study, we unveil the positive role of OTUB1 in osteoblast-mediated bone formation by maintaining FGFR2 stability and the osteogenesis effects of OTUB1 provide an optical therapeutic strategy to alleviate osteoporosis."

reach
"To unravel which mechanism is involved in OTUB1-mediated FGFR2 regulation, we mutated E2-binding residue aspartic acid (D) 88, catalytic core residues cysteine (C) 91 and histidine (H) 265 in OTUB1."
