GAMMA-VPE gamma vacuolar processing enzyme [Arabidopsis thaliana (thale cress)] - Gene

Summary

Go to the top of the page Help

Gene symbol: GAMMA-VPE
Gene description: gamma vacuolar processing enzyme
Primary source: Araport:AT4G32940
Locus tag: AT4G32940
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F26P21.60; F26P21_60; gamma vacuolar processing enzyme; GAMMAVPE
Summary: Encodes a vacuolar processing enzyme belonging to a novel group of cysteine proteinases that is expressed in vegetative organs and is upregulated in association with various types of cell death and under stressed conditions. They are essential in processing seed storage proteins and for mediating the susceptible response of toxin-induced cell death.

What's a GeneRIF?

gammaVPE is a crucial processing enzyme for xylem fiber cells PCD during stem development
Title: γVPE plays an important role in programmed cell death for xylem fiber cells by activating protease CEP1 maturation in Arabidopsis thaliana.
The presented integrative mechanisms of proteolysis and ligation (transpeptidation) explain the interdependence of legumain and its preferred substrates and provide a rational framework for engineering optimized proteases, ligases, and substrates. [legumain gamma]
Title: Structural analyses of Arabidopsis thaliana legumain γ reveal differential recognition and processing of proteolysis and ligation substrates.
the activation of Arabidopsis gamma-VPE was mediated by MPK6 and played an important role in heat shock-induced Arabidopsis programmed cell death
Title: MAP Kinase 6-mediated activation of vacuolar processing enzyme modulates heat shock-induced programmed cell death in Arabidopsis.
gammaVPE is the proteinase that exhibits a caspase-1 activity
Title: Vacuolar processing enzyme is essential for mycotoxin-induced cell death in Arabidopsis thaliana.
