WebJul 13, 2024 · The ARM domains of PUB12/13 are essential for interaction with FLS2–BAK1 complex and phosphorylation by BAK1 ( Zhou et al., 2015a ). In vitro ubiquitination assay showed that PUB12 and PUB13 specifically polyubiquitinate FLS2, but not BAK1 and BIK1, which promotes the degradation of FLS2 ( Lu et al., 2011 ). WebThe Arabidopsis pattern-recognition receptor Flagellin Sensing 2 (FLS2) recognizes bacterial flagellin and initiates immune signaling through association with BAK1. ... et al. Regulation of Arabidopsis brassinosteroid receptor BRI1 endocytosis and degradation by plant U-box PUB12/PUB13-mediated ubiquitination. Proc. Natl. Acad. Sci. USA 2024 ...
Arabidopsis ubiquitin ligase PUB12 interacts with and negatively
WebFeb 5, 2024 · PUB12 and PUB13 were initially identified as BAK1-interacting E3 ligases that regulate FLS2 stability in flg22 signaling (14, 15). Recently, PUB12 and PUB13 were … WebNov 28, 2024 · Consequently, FLS2 is ubiquitinated by PUB12/PUB13 and then degraded through a 26S proteasome pathway. In a similar manner, rice PRR Xa21 is negatively regulated by the protein phosphatase 2C and ubiquitinated by the RING-finger ubiquitin E3 ligase XB3 . However, in contrast to PUB12/PUB13, XB3 positively regulates Xa21 … highway 2 bicycle parts

WebRemarkably, Lu et al. (2011) recently reported that the PRR FLAGELLIN-SENSING2 (FLS2), a LRR receptor-like kinase , is a target of the E3 ligases PUB12 and PUB13 via the UPS. When induced by the bacterial PAMP elicitor flagellin, FLS2 is polyubiquitinated and degraded by PUB12/13. WebOct 21, 2024 · PUB13 is an active E3 ubiquitin ligase and that the intact U-box domain is required for the E3 ligase activity. study has revealed a unique regulatory circuit of direct ubiquitination and turnover of FLS2 by BAK1-mediated phosphorylation and recruitment of specific E3 ligases (PUB12,PUB13) for attenuation of immune signaling WebPUB12 and PUB13 polyubiquitinate FLS2 and promote flagellin-induced FLS2 degradation, and the pub12 and pub13 mutants displayed elevated immune responses to flagellin treatment. Our study has revealed a unique regulatory circuit of direct ubiquitination and turnover of FLS2 by BAK1-mediated phosphorylation and recruitment of specific E3 … small solar panels for electronics
