USP12 deubiquitinates PPM1B. 6 / 6
| 6

reach
"Yang et al. found that USP12 and USP46 deubiquitinates and stabilizes PPM1B to regulate chemokine production in tumor cells ( Yang et al., 2021 )."

reach
"USP12 regulates chemokine production by deubiquitinating PPM1B."

reach
"The interaction between PPM1B and USP12 was then validated (Fig. 4c), raising the question of whether USP12 deubiquitinates PPM1B."

reach
"The ubiquitination experiments showed that ectopic expression of USP12 but not the C48S mutant decreased the levels of PPM1B polyubiquitination (Fig. 4d)."

reach
"We found that USP12 downregulation caused insufficient deubiquitination of PPM1B and thereby facilitated tumour growth by promoting the generation of the protumourigenic milieu."

reach
"For example, USP12 is described above as promoting NF-κB activation for NLRP3 inflammatory microsome production, but in NSCLC it inhibits NF-κB signaling activity and regulates chemokine secretion by deubiquitinating and stabilizing PPM1B."
