Abstract

Sestrins are highly conserved stress-inducible proteins capable of suppressing the production of ROS and signalling through mTORC1. Here we report a study of human sestrin1 (sesn1) and sestrin2 (sesn2) proteins produced in a pET28^(+) vector based prokaryotic system. Mass spectrometry analysis, western blot and surface plasmon resonance (SPR) of affinity purified sesn1 and sesn2 proteins confirmed their identity; biophysical characteristics were observed using circular dichroism (CD) showing that sesn1 and sesn2 have a predominant α-helical structure. Here we describe a simple, one step purification process to purify a large amount of sestrin proteins with significant yield. Further study of recombinant human sestrins may further facilitate the understanding of their roles in eukaryotic cells.
