2 First Multicenter Experiment of Chr16 Spanish Consortium Chr 16 proteins database List of 06 “unknown” proteins List of proteotypic peptides of the 06 unknown proteins ensembl_gene_id external_ gene_iddescriptionstrandband transcript_ count ENSG TMC7 transmembrane channel-like 7 [Source:HGNC Symbol;Acc:23000] 1p12.32 ENSG NLRC5 NLR family, CARD domain containing 5 [Source:HGNC Symbol;Acc:29933] 1q1331 ENSG C16orf48 chromosome 16 open reading frame 48 [Source:HGNC Symbol;Acc:25246] q22.11 ENSG ATF7IP2 activating transcription factor 7 interacting protein 2 [Source:HGNC Symbol;Acc:20397] 1p13.26 ENSG TMEM188 transmembrane protein 188 [Source:HGNC Symbol;Acc:26759] 1q12.13 ENSG FA2H fatty acid 2-hydroxylase [Source:HGNC Symbol;Acc:21197] q23.12

3 Sample distribution (proteins extracts) Francesc Canals: MCF7 epitelial cells (500µg/50µL; 6M Urea, ammonium) bicarbonate 50mM Ignacio Casal:CCD-18 fibroblast cells (700µg/100µL; 6M Urea, ammonium) bicarbonate 50mM Manuel Fuentes:Ramos cell line MCF7CCD-18Ramos SDS-PAGE: - 12% acrilamide -100 µg/ sample - Coloidal Coomassie - Cutted 15 slides/fractions - manual digestion with trypsin

4 LC-MSMS conditions LC system Gradient to 35%ACN in 90min. Column length: 25 cm Inclusion List MSMS analysis (FAIMS, top 5) Incorporate a list of 131 parent ions or m/z in the High Resolution MS experiment Resolution: Maximum inject time MS: Velos 120 msec, FT 250 msec MSMS: Velos 100 msec, FT 300 msec Minimum signal required: 100 Number of microscans: 1 Precursor isolation width: 2 m/z units Data dependent MSMS analysis (top 10) Resolution: Maximum inject time MS: Velos 120 msec, FT 250 msec MSMS: Velos 100 msec, FT 300 msec Minimum signal required: 500 Number of microscans: 1 Precursor isolation width: 2 m/z units
