USP — Pisum sativum

Summary

PsUSP (PSAT7G240560) on garden pea chromosome 7LG7 encodes a universal stress protein (UspA) domain-containing protein with protein folding chaperone and nucleic acid binding activity. The gene is associated with protein folding, RNA folding, and responses to oxidative stress, heat, and cold. It is also associated with embryogenesis, microsporogenesis, pollen development, lateral root formation, and ecdysteroid anabolism. Localisation evidence places the product in the cytoplasm, nucleus, cytosol, plasmodesma, and plasmalemma. Related genes in other species are linked to salt stress tolerance, male fertility, seed germination, and nucleotide sugar biosynthesis. Sequence similarity links the family further to traits including protein content, root length, seed maturation, and disease tolerance.
