CC   -!- FUNCTION: Transcription factor that regulates the expression of the
CC       gene clusters that mediate the biosynthesis of the host-selective
CC       toxins (HSTs) AK-toxins responsible for Japanese pear black spot
CC       disease by the Japanese pear pathotype (Probable). AK-toxins are esters
CC       of 9,10-epoxy 8-hydroxy 9-methyldecatrienoic acid (EDA)
CC       (PubMed:22846083). On cellular level, AK-toxins affect plasma membrane
CC       of susceptible cells and cause a sudden increase in loss of K(+) after
CC       a few minutes of toxin treatment (PubMed:22846083).
CC       {ECO:0000303|PubMed:22846083, ECO:0000305|PubMed:10975654}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00227}.
CC   -!- MISCELLANEOUS: Gene clusters encoding host-selective toxins (HSTs) are
CC       localized on conditionally dispensable chromosomes (CDCs), also called
CC       supernumerary chromosomes, where they are present in multiple copies
CC       (PubMed:10975654). The CDCs are not essential for saprophytic growth
CC       but controls host-selective pathogenicity (PubMed:10975654).
