Zera®, a novel technology for stable accumulation and easy recovery of recombinant proteins in eukaryotic protein-production hosts

Abstract

First paragraph (this article has no abstract) Subcellular targeting of proteins in host cells is one of the most important issues in protein production. Stability, folding, and post-translational modifications depend on where proteins are sorted. Besides secretion, ER appears as an efficient compartment to accumulate proteins, as demonstrated by the frequent use of K/HDEL fused to the C-terminus of a protein to retain and accumulate recombinant proteins in the endoplasmic reticulum (ER) of the cell hosts.
