摘要: In PNAS, Jahan et al. (1) describe a new role for the ubiquitin-specific protease 12 (USP12) deubiquitinase in T-cell receptor (TCR) signaling. Among other findings, authors report that USP12 is exported from nucleus to cytosol upon TCR activation. Although experimental evidence they provide consistent with this model, I believe some of their results would require more detailed description support claims better.
