Enriched tight junction (TJ) and adherens junction (AJ) proteins tagged by biotin ligase fused to occludin and claudin-4.

Numbers in the columns for biotin ligase constructs are average normalized PSM/OPNx1000 from 3-fold enriched proteins compared to the biotin ligase alone [11]. PSM is based on peptide fragmentation and subsequent sequencing by collision-induced dissociation (CID) where the same precursor mass can be sequence more than once. Numbers in parenthesis shows that the protein is enriched, however not in the top 150. Not detectable (ND) means that a protein is not enriched. Data from ZO-1 and E-cad are taken from previously published data [10,11]. If a reference is not listed in the far right column, UniProt is the source of protein localization/function. Italic proteins fall into more than one functional category, for example exocytosis and endocytosis.Enriched tight junction (TJ) and adherens junction (AJ) proteins tagged by biotin ligase fused to occludin and claudin-4.
