Hsp70s comprise a deeply conserved chaperone family that has a central role in maintaining protein homeostasis. In humans, Hsp70 client specificity is provided by 49 different co-factors known as J domain proteins (JDPs). However, the cellular function and client specificity of JDPs have largely remained elusive. We have combined affinity purification-mass spectrometry (AP-MS) and proximity-dependent biotinylation (BioID) to characterize the ... [more]

Additional Notes

High confidence interactions were identified as having an average probability of the identified interaction (AvgP) >= 0.98. The associated score represents the fold change of spectral counts (or intensities) for each individual interaction.
