THEMIS is an essential T-cell receptor signal modulator critical for T-cell development and peripheral homeostasis; however, the machinery governing its protein stability remains elusive. Utilizing unbiased CRISPR/Cas9 screening integrated with affinity purification-mass spectrometry, we identify UB...

CRISPR-Cas9 Screening Identifies UBE3C as a Top Negative Regulator of THEMIS Protein Expression
A hallmark of neurodegenerative diseases such as Parkinson’s Disease is the progressive loss of proteostasis, leading to the conversion of misfolded proteins into aggregates and subsequent cytotoxicity. To combat this toxicity, cells have evolved degradation pathways (ubiquitin-proteasome system and...
