Enzyme Function FUNCTION: Secreted effector that acts as an elicitor of hypersensitive response (HR) specifically on plants carrying defense protein Rpi-blb2 (PubMed:19794118). Enhances P.infestans colonization of Nicotiana benthamiana leaves (PubMed:30329083). Interacts with, and subsequently prevents secretion into the apoplast of the host papain-like cysteine protease C14, thus promoting virulence by interfering with the execution of host defenses (PubMed:22143776). Associates with calmodulin at the host plasma membrane to interfere with plant defense-associated calcium signaling in hosts (PubMed:30984224). {ECO:0000269|PubMed:19794118, ECO:0000269|PubMed:22143776, ECO:0000269|PubMed:30329083, ECO:0000269|PubMed:30984224}.
