USP — Phaseolus vulgaris

Summary

PHAVU_010G008900, designated PvUSP (also known as PvUSP17), encodes a protein containing a Universal Stress Protein (UspA) domain and a Rossmann-like fold, with annotated molecular functions as a protein folding chaperone and nucleic acid binding protein. In French bean, this gene is associated with RNA folding, nitric oxide storage, embryogenesis, microsporogenesis, protein folding, and responses to oxidative, heat, and cold stress. It localizes to the plasmodesma, cytosol, plasmalemma, cytoplasm, and nucleus. PvUSP is associated with abscisic acid sensitivity. Studies of related genes in other species connect the USP family to traits including seed maturation, pollen fertility, abiotic stress tolerance, root length, protein content, disease tolerance, and male fertility, as well as processes such as seed germination, pollen development, and antifungal defense.
