BP80 (TRAESCS4D02G172100) — triticum aestivum

Summary

TRAESCS4D02G172100 (symbol BP80, also known as Vsr1) on wheat chromosome 4D encodes a vacuolar sorting signal receptor with clathrin-binding, protease-binding, calcium-binding, cysteine-type peptidase and ubiquitin ligase activities. The protein contains PA, cEGF and VSR_TRX domains and localizes to clathrin-coated vesicle membranes, Golgi, TGN, endosomes and secretory vesicles. It is associated with Golgi-to-vacuole transport, vacuolar protein sorting, protein localization to the plasma membrane, response to karrikin and nitrate, transition metal and calcium transport, proton transmembrane transport, positive regulation of flavonoid anabolism, and regulation of the hypersensitive response. The gene is linked to grain weight, grain yield, plant height, root thickness, leaf and stem senescence, heterosis, drought tolerance, disease tolerance, IAA content, osmotic stress tolerance, abscisic acid biosynthesis, and auxin signalling pathways. Studies of related genes in other species connect the family to seed storage protein sorting, senescence, and pattern-triggered immunity.
