This function retrieves a list of organelle markers or, if no
species
is provided, prints a description of available
marker sets. The markers can be added to and MSnSet
using
the addMarkers
function.
pRolocmarkers(species)
The species of interest.
Prints a description of the available marker lists if
species
is missing or a named character with organelle
markers.
The markers have been contributed by various members of the
Cambridge Centre for Proteomics, in particular Dr Dan Nightingale
for yeast, Dr Andy Christoforou and Dr Claire Mulvey for human, Dr
Arnoud Groen for Arabodopsis and Dr Claire Mulvey for mouse. In
addition, original (curated) markers from the pRolocdata
datasets have been extracted (see pRolocdata
for details
and references). Curation involved verification of publicly
available subcellular localisation annotation based on the
curators knowledge of the organelles/proteins considered and
tracing the original statement in the literature.
These markers are provided as a starting point to generate reliable sets of organelle markers but still need to be verified against any new data in the light of the quantitative data and the study conditions.
addMarkers
to add markers to an
MSnSet
and markers
for more information about
marker encoding.
