PBL2_ARATH | function | Involved in disease resistance signaling (PubMed:20413097, PubMed:23951354, PubMed:26355215). Contributes to pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) signaling and defense responses downstream of FLS2 (PubMed:20413097). Acts as a BIK1 decoy and enables Xanthomonas campestris AvrAC/XopAC detection; X.campestris effector AvrAC/XopAC-mediated uridylylation promotes the formation of a complex with RKS1 and RPP13L4/ZAR1 which, in turn, activates effector-triggered immunity (ETI) against X.campestris (PubMed:23951354, PubMed:26355215, PubMed:30948526). Promotes, when uridylylated by AvrAC/XopAC, the release of ADP from the inactive RKS1-ZAR1 complex, thus activating the resistosome (PubMed:30948526). |
PBL2_ARATH | similarity | Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. |
PBL2_ARATH | subcellular location | Predominantly localized at the plasma membrane. |
PBL2_ARATH | tissue specificity | Strongly expressed in leaves, moderately in roots, and barely in flowers, mostly in pedicels. |
