PCS1 — Nicotiana attenuata

Summary

A4A49_03783 (PCS1) in coyote tobacco (Nicotiana attenuata) on scaffold00432 encodes an aspartic endopeptidase, belonging to the pepsin-like plant aspartic peptidase A1 family. The gene is associated with phytochelatin anabolism, cellular detoxification, and response to cadmium, as well as regulation of programmed cell death, hypersensitivity, and defense response. It is also linked to response to vitamin C, response to light stimulus, cellular response to hypoxia, and homeostasis. The encoded protein is localized to the apoplast, Golgi complex, and extracellular space. Studies of related genes in other species link the family to oxidative stress response.
