AN1 — Zea mays

Summary

ZM00001EB418570, designated AN1 on maize chromosome 10, encodes a papain-like cysteine peptidase with thiol endopeptidase activity and cysteine-type peptidase activity, and is associated with proteinase-activated receptor binding. The gene is associated with pigment accumulation, anthocyanin anabolism, pigmentation, phytoalexin biosynthesis, secondary metabolism, programmed cell death involved in cell development, leaf senescence, seed germination, proteolysis, responses to abscisic acid, ethylene, and gibberellin, auxin transport and signaling, and response to thirst. The product localizes to vacuoles, lysosomes, the ER lumen, senescence-associated vacuoles, and protein storage vacuoles. Trait associations include plant height, root length, drought tolerance, and salt tolerance. Studies of related genes in other species link the family to nitrogen and cytokinin content.
