Triplicate FLAG-Immunoprecipitations of FLAG-tagged FBXO7 overexpressed in FBXO7-/- PSMF1-/- HEK293T cells co-overexpressed with full length PI31(1-271), PI31∆PRR (1-151), or without PI31 (empty vector). wild type HEK293T containing FLAG-tagged eGFP samples represent a negative control IP Identities of each sample and the TMT channels associated with each are included in as a table with this dataset.
