[[ | [[https://www.uniprot.org/uniprot/BAK1_ARATH BAK1_ARATH]] Dual specificity kinase acting on both serine/threonine- and tyrosine-containing substrates. Controls the expression of genes associated with innate immunity in the absence of pathogens or elicitors. Involved in brassinosteroid (BR) signal transduction. Phosphorylates BRI1. May be involved in changing the equilibrium between plasma membrane-located BRI1 homodimers and endocytosed BRI1-BAK1 heterodimers. Interaction with MSBP1 stimulates the endocytosis of BAK1 and suppresses brassinosteroid signaling. Acts in pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) via its interaction with FLS2 and the phosphorylation of BIK1. Involved in programmed cell death (PCD) control. Positively regulates the BR-dependent plant growth pathway and negatively regulates the BR-independent cell-death pathway.<ref>PMID:17600708</ref> <ref>PMID:17583510</ref> <ref>PMID:18694562</ref> <ref>PMID:18667726</ref> <ref>PMID:19124768</ref> <ref>PMID:20018402</ref> <ref>PMID:20404519</ref> <ref>PMID:21350342</ref> [[https://www.uniprot.org/uniprot/HPAB2_PSESM HPAB2_PSESM]] Effector protein involved in gene-for-gene resistance in tomato plants. It is recognized by the host Pto resistance protein and elicits Pto and Prf-dependent hypersensitive response (HR) and programmed cell death (PCD), resulting in host immunity. In susceptible plants, acts as a virulence factor by suppressing PCD and HR-based plant immunity. This function requires its E3 ubiquitin ligase activity probably by recruiting E2 enzymes and transferring ubiquitin molecules to cellular proteins involved in regulation of PCD and targeting them for degradation. Also, induces expression of host genes involved in ethylene biosynthesis and signaling, in particular ACO1 and ACO2, encoding the ethylene-forming enzyme ACC oxidase.<ref>PMID:12062102</ref> <ref>PMID:12505984</ref> <ref>PMID:16167902</ref> <ref>PMID:16477026</ref> <ref>PMID:16373536</ref> | ||
