A cell-permeant peptide corresponding to the cUBP domain of USP5 reverses inflammatory and neuropathic pain.

We have shown that Cav3.2 channel surface density is strongly regulated by the ubiquitination machinery and we identified the deubiquitinase USP5 as a Cav3.2 channel interacting protein and regulator of its cell surface expression. We also reported that USP5 is upregulated in chronic pain conditions. Conversely, preventing its binding to the channel in vivo mediates analgesia in inflammatory and neuropathic pain models.enT-type channelsCav3.2USP5chronic painTAT-cUBP1-USP5 peptidediabetic neuropathyComplete Freund's Adjuvantjournal articlehttp://dx.doi.org/10.1177/1744806916642444
