European Journal of Immunology Supporting Information for Eur. J. Immunol. 10.1002/eji.200838136 Features of TAP-independent MHC class I ligands revealed by quantitative mass spectrometry Andreas O. Weinzierl, Despina Rudolf, Nina Hillen, Stefan Tenzer, Peter van Endert, Hansjörg Schild, Hans-Georg Rammensee and Stefan Stevanović © 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim www.eji-journal.eu Supplementary tables Supplementary table 1 A quantitative analysis of protein and mRNA levels demonstrates partial deletion of chromosome 6p21.3. The analysis comprised constitutive proteasomal subunits (PSMB1, 2 and 5), immunoproteasomal subunits (LMP7, 2 and MECL1), subunits of the immunoproteasomal regulator PA28 (PSME1-3), proteins of the HLA peptide loading complex (TAP1 and 2, tapasin, calreticulin, calnexin and PDIA3), HLA class I and II (HLA-A, -B, -C, - DR, -DP and -DQ), the endoplasmic reticulum aminopeptidase associated with antigen processing (ERAAP) and proteins of the SEC61 translocon which can be involved in peptide export from the ER. Genes encoded in the deleted region of chromosome 6p21.3 in LCL721.174 cells are highlighted in bold.

HLA presentation ratios, protein and mRNA expression ratios were calculated betweenLCL721.174 and LCL721.45. Signal sequence prediction was performed using the SwissProt database or SignalP (http://www.cbs.dtu.dk/services/SignalP/). SYFPEITHI and BIMAS scores were calculated using web based software (http://www.syfpeithi.de, http://www- bimas.cit.nih.gov/molbio/hla_bind).
