Des-ubiquitin is formed when a cysteine protease cleaves two carboxy-terminal glycine residues from ubiquitin.
There are no datasets associated with this biomarker.
The following organs have data associated with this biomarker…
Cathepsin B, which is a cysteine protease, cleaves 2 terminal glycine residues of ubiquitin generating des-ubiquitin. Both monomeric ubiquitin and des-ubiquitin corresponding to m/z values 8,565 and 8,451 are among the 9 candidates of the signature described in the Rahman 9-marker MALDI MS panel for Lung Cancer study.
Des-ubiquitin belongs to a 9-member panel that provides a quantitative measure of the probability of having lung cancer that goes beyond the histological evaluation of preinvasive lesions. The identified members of the panel are TMSB4X (Thymosin beta-4), Ubiquitin, des-ubiquitin, ACBP, CSTA, Cytochrome C, and MIF.

The National Cancer Institute's Division of Cancer Prevention has released a new funding opportunity to solicit organ-specific applications for Biomarker Developmental Laboratories (BDLs), one of the four scientific units of the recently funded Early Detection Research Network (EDRN). The EDRN is a national infrastructure funded to discover, develop, and validate biomarkers for risk assessment, detection, and molecular diagnosis and prognosis of early cancer. BDLs are responsible for the discovery, development, characterization, and testing of new, or the refinement of existing, biomarkers and biomarker assays for risk assessment, detection, and molecular diagnosis and prognosis of cancers.
The existing BDLs are primarily focused on ovary and gastrointestinal cancers. The proposed BDLs (to be supported under this funding opportunity) should be focused on one or more of the following cancers: breast, prostate and other genitourinary organs, or lung. In addition, cancers with rapidly rising incidence rates, e.g., endometrial, hepatocellular, kidney, thyroid, oropharyngeal cancers, and/or cancers with unique etiology, e.g., mesothelioma, will be considered.
The newly funded units of the Early Detection Research Network will be announced later in April. Successful applicants have already been notified. Those researchers who were not successful during the last round of applications are encouraged to apply to this opportunity.
