PXD066071

PXD066071 is an original dataset announced via ProteomeXchange.

Title	Dataset 1 from 'Atlas of the proteasome interactome by in situ structural biology'
Description	In the hRpn1 pulldown(dataset1 and 2), we identified 2793 unique residue pairs (877 inter-protein) at a 2% residue-pair target-decoy false discovery rate (FDR), with an additional threshold limiting the protein-protein FDR to 5% (Lenz et al., 2021 PMID: 34117231). The hRpn11 pulldown (dataset 3) yielded 3371 unique residue pairs (1847 inter-protein) at the same FDR threshold. When combined, the two datasets included 5364 non-redundant crosslinked residue pairs. This includes 2266 hetero-protein links describing 278 PPIs, with a combined estimated PPI-FDR of 7.3%
