Identification of α-tubulin as an autoantigen recognized by sera from patients with neuropsychiatric systemic lupus erythematosus.
2011
In a previous study we found in 50% of patients with neuropsychiatric manifestations of systemic lupus erythematosus (NP-SLE) organ specific antibodies to 45-56 kD proteins in a 100,000 g supernatant (SN) from bovine brain mitochondria. Aim of the present study was to identify the corresponding target antigen. A 100,000 g SN from bovine brain mitochondria was applied to SDS-gel electrophoresis. A 50 kD band recognized by sera from patients with NP-SLE in the Western blot (WB) was excised from the gels and applied to mass spectrometry. The identified protein was expressed in Escherichia coli and retested against sera from eleven patients with NP-SLE (severe symptoms n=6, mild symptoms n=5), …

Quantitative Analysis of Prion-Protein Degradation by Constitutive and Immuno-20S Proteasomes Indicates Differences Correlated with Disease Susceptib…
2004
Abstract The main part of cytosolic protein degradation depends on the ubiquitin-proteasome system. Proteasomes degrade their substrates into small peptide fragments, some of which are translocated into the endoplasmatic reticulum and loaded onto MHC class I molecules, which are then transported to the cell surface for inspection by CTL. A reliable prediction of proteasomal cleavages in a given protein for the identification of CTL epitopes would benefit immensely from additional cleavage data for the training of prediction algorithms. To increase the knowledge about proteasomal specificity and to gain more insight into the relation of proteasomal activity and susceptibility to prion diseas…
