Store at -20°C; make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
For reconstitution add 50 µL of sterile water.
Specific Species Reactivity: Arabidopsis thaliana
PROPEP1 is a small Arabidopsis thaliana gene whose transcript is induced in damaged or stressed leaf tissue and encodes a short, highly charged, non-secreted cytosolic precursor protein (AtProPep1) of 92 amino acids that lacks an N-terminal signal peptide; the biologically active product is AtPep1, a 23 amino-acid peptide embedded in the C-terminal region of the precursor and released to act as an endogenous danger signal. Functionally, AtPep1 amplifies innate immune and wound-associated responses by promoting defense gene transcription (including PDF1.2/defensin), stimulating reactive oxygen species production (H2O2), and reinforcing jasmonate/ethylene-linked defense signaling; constitutive PROPEP1 expression is sufficient to drive constitutive defense gene activation and is associated with enhanced resistance to certain pathogens, consistent with PROPEP1 acting upstream of receptor-mediated danger signaling through PEPR-family cell-surface receptors.
