Seed storage proteins are synthesized as precursors on the endoplasmic reticulum (ER) and then transported to protein storage vacuoles, where they are processed into mature forms. MAG2 body is a novel structure found in cells, containing storage protein precursors and endoplasmic reticulum molecular chaperones. It has a core part with high electron density and a matrix part with low electron density. The core fraction consists of precursors of 2S albumin, and the matrix fraction contains precursors of 12S globulin as well as immunoglobulin heavy chain-binding protein and protein disulfide isomerase.
Lifeasible provides functional analysis of the MAG2 body, including storage protein precursors and molecular chaperones, to help our customers worldwide in the field of plant science. Our platform is equipped with cutting-edge facilities and professional experts to support research. Here, we provide various services according to customers' demands.
