== Function ==
[[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>
