PR10 — Phaseolus vulgaris

Summary

PHAVU_003G109100, designated PvPR10, encodes a protein belonging to the Bet v I/MLP (major latex protein) and START-like domain superfamily, characteristic of the PR10 family. The product exhibits multiple molecular functions annotated on this gene, including melatonin, cytokinin, and abscisic acid binding, RNA nuclease activity, protein phosphatase inhibitor activity, hydrolase activity, signaling receptor activity, and calcium ion binding. PvPR10 is associated with the downregulation and regulation of photosynthesis, seed germination, proteolysis, nodulation, ABA signaling, root development, and defense response. It localizes to the cytosol, cytoplasm, and nucleus. The gene is also linked to drought tolerance. Related genes in other species, based on sequence similarity, connect the PR10 family to an endonuclease activity (EC 3.1.27.-).
