Disease relevance of UCHL3

  • Because the amino acid sequence of UCH-L1 is similar to that of other ubiquitin C-terminal hydrolases, including the ubiquitously expressed UCH-L3, which appear to be unconnected to neurodegenerative disease, the structure of UCH-L1 and the effects of disease associated mutations on the structure and function are of considerable importance [1].
  • UCH-L3 mRNA level was significantly upregulated in breast cancer tissue compared to adjacent normal breast tissue (P < 0.005), and UHC-L1 mRNA level also showed a non-significant increase in tumor tissue compared to adjacent normal breast tissue [2].
  • One fraction that exhibited reactivity with 9/15 colon cancer sera was subjected to mass spectrometry leading to the identification of ubiquitin C-terminal hydrolase isozyme 3 (UCH-L3) as a constituent [3].

Associations of UCHL3 with chemical compounds

  • By utilizing high-throughput screening (HTS) to find inhibitors and traditional medicinal chemistry to optimize their affinity and specificity, we have identified a class of isatin O-acyl oximes that selectively inhibit UCH-L1 as compared to its systemic isoform, UCH-L3 [9].
  • UCH-6 belonged to members of the UCH family containing highly conserved Cys, His, and Asp domains and showed 86% amino acid identity to human UCH-L3 [6].
 

Enzymatic interactions of UCHL3

  • However, UCH-L3 had no detectable activity toward ubiquitinated I kappa B alpha, thus suggesting a degree of enzymatic specificity in the deubiquitination of I kappa B alpha [10].
 

Other interactions of UCHL3

  • The activity of the C-terminal hydrolases UCH-L3 and UCH37 was upregulated in the majority of tumor tissues compared to the adjacent normal tissues [11].
  • To develop an enzymatic assay for the search of UCH-L3 and USP2 inhibitors, C-terminally labeled ubiquitin substrates were enzymatically synthesized [12].
  • To determine whether specificity may be conferred by recognition of a primary cognate sequence, the substrate preferences of two DUBs, UCH-L3 and isopeptidase T (IsoT), were profiled using a positional scanning branched peptide library [13].
