drug discovery in the ubiquitin field

Access to well defined ubiquitinated peptides and conjugates, which could so far not be routinely produced (bio)chemically, is of paramount importance for screening assays for the identification of new drugs, as well as for fundamental research and structural studies. Find out about how our reagents enables research in the three stages of early drug discovery.

custom made reagents

With our UbiQ technologies we are able to fully synthesize site-selective ubiquitinated peptides of native conformation, using automated solid phase peptide synthesis. This enables us to synthesize any custom made peptides.

  • UbiQ-news: launch of an activity-based probe for the deubiquitinating enzyme OTULIN

    23 October 2017

    Hereby we present UbiQ-121 as an activity-based probe for OTULIN, a deubiquitinating enzyme that is specific for Met1 linked ubiquitin chains and acts as a negative regulator of nuclear factor κB signaling and immune homeostasis. UbiQ-121 is based on Met1 linked diubiquitin in which G76 of the distal ubiquitin is replaced by an electrophilic dehydroalanine (Dha) residue. The catalytic cysteine residue of OTULIN reacts in a covalent manner with the Dha residue and as such UbiQ-121 captures OTULIN in its active conformation .....(more)
