PR1 — Asparagus officinalis

Summary

A4U43_C02F21580, designated PR1 on asparagus chromosome 2, encodes a Bet v I/Major latex protein domain-containing protein belonging to the Bet_v_I/MLP and START-like domain superfamilies. The product exhibits annotated nuclease, hydrolase, abscisic acid binding, signaling receptor, and protein phosphatase inhibitor activities. It is associated with defense response, response to wounding, ABA signaling, and flavonoid anabolism, and localises to both the cytoplasm and nucleus. Studies of related genes in other species link the family to an uncharacterised nuclease activity (EC 3.1.27.-).
