Details
Abstract: The proteomic composition of the Arabidopsis Golgi apparatus
is currently reasonably well documented; however little is known about
the relative abundances between different proteins within this
compartment. Accurate quantitative information of Golgi resident
proteins is of great importance: it facilitates a better understanding
of the biochemical processes which take place within this organelle,
especially those of different polysaccharide synthesis pathways. Golgi
resident proteins are challenging to quantify since the abundance of
this organelle is relatively low within the cell. In this study an
organelle fractionation approach, targeting the Golgi apparatus, was
combined with a label free quantitative mass spectrometry (MS),
data-independent acquisition (DIA) method employing ion mobility
separation known as LC-IMS-MSE (or HDMSE), to simultaneously localize
proteins to the Golgi apparatus and assess their relative quantity. In
total 102 Golgi localised proteins were quantified. These data provide
new insight into Golgi apparatus organization and demonstrate that
organelle fractionation in conjunction with label free quantitative MS
is a powerful and relatively simple tool to access protein organelle
localisation and their relative abundances. The findings presented
open a unique view on the organization of the plant Golgi apparatus,
leading towards novel hypotheses centered on the biochemical processes
of this organelle.
These data are a concatenation of 2 LOPIMS gradients, labelled
gradient A and B, each with 10 fractions.
