While several automated solutions are available for in-gel digestion particularly of small cylindric gel plugs derived from 2D gels, the processing of larger 1D gel-derived gel bands with liquid handling work stations is less well established in the field. Here, we introduce a digestion device tailored to this purpose and validate its performance in comparison to manual in-gel digestion. For relative quantification purposes, we extend the in-gel digestion procedure by iTRAQ labeling of the tryptic peptides and show that automation of the entire workflow results in robust quantification of proteins from samples of different complexity and dynamic range. We conclude that automation improves accuracy and reproducibility of our iTRAQ workflow as it minimizes the variability in both, digestion and labeling efficiency, the two major causes of irreproducible results in chemical labeling approaches."],["dc.description.sponsorship","Max Planck Society"],["dc.identifier.doi","10.1002/pmic.201200366"],["dc.identifier.isi","000318049800005"],["dc.identifier.pmid","23456960"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/30059"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1615-9853"],["dc.title","An automated in-gel digestion/iTRAQ-labeling workflow for robust quantification of gel-separated proteins"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Their long-term actions are accomplished by promoting the expression of specific genes whereas faster responses are achieved by direct phosphorylation of downstream effectors located throughout the cell. In this study we determined that hERK1 translocates to the mitochondria of HeLa cells upon a proliferative stimulus. In the mitochondrial environment, hERK1 physically associates with (i) at least 5 mitochondrial proteins with functions related to transport (i.e. VDAC1), signalling, and metabolism; (ii) histones H2A and H4; and (iii) other cytosolic proteins. This work indicates for the first time the presence of diverse ERK-complexes in mitochondria and thus provides a new perspective for assessing the functions of ERK1 in the regulation of cellular signalling and trafficking in HeLa cells."],["dc.format.extent","18"],["dc.identifier.doi","10.1371/journal.pone.0007541"],["dc.identifier.fs","569017"],["dc.identifier.pmid","19847302"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5824"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60253"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.publisher","Public Library of Science"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 2.5"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.5"],["dc.subject.ddc","610"],["dc.subject.mesh","Amino Acid Sequence"],["dc.subject.mesh","Cell Proliferation"],["dc.subject.mesh","Gene Expression Profiling"],["dc.subject.mesh","Gene Expression Regulation, Enzymologic"],["dc.subject.mesh","Gene Expression Regulation, Neoplastic"],["dc.subject.mesh","Glutathione Transferase"],["dc.subject.mesh","Hela Cells"],["dc.subject.mesh","Humans"],["dc.subject.mesh","MAP Kinase Signaling System"],["dc.subject.mesh","Mitochondria"],["dc.subject.mesh","Mitogen-Activated Protein Kinase 3"],["dc.subject.mesh","Molecular Sequence Data"],["dc.subject.mesh","Proteomics"],["dc.subject.mesh","Sequence Homology, Amino Acid"],["dc.subject.mesh","Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization"],["dc.title","A new paradigm for MAPK: structural interactions of hERK1 with mitochondria in HeLa cells."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
