USP15

A gene on chromosome 12q14 that encodes an enzyme which deubiquitinates Lys-48-linked polyubiquitinated proteins, targeting them against proteasomal degradation. USP15 protects APC and HPV type-16 protein E6 against degradation via the ubiquitin proteasome pathway. It is expressed in skeletal muscle, kidneys, heart, placenta, liver, thymus, lungs and ovaries.

USP15, which is highly similar with USP4 [69], also is involved in Wnt signaling and bone formation [91].

USP15, which regulates osteoblast function and bone formation, is connected to osteoclast function too [76].

To date, several DUBs are found to regulate osteoblast function (USP4, USP7, USP9x, USP15, UCH-l3, and MYSM1) and osteoclast function (CYLD, USP15, USP18, A20, and POH1) (Table 2).

Deubiquitinating Enzymes and Bone Remodeling

Corbin focuses on a novel therapeutic approach to treat various inflammation-based diseases via inhibition of the ubiquitin-specific protease 15 (USP15).

Maxime Ranger, President and Chief Executive Officer of Corbin, commented, Corbin recognized the high value and great potential of Proteorexs innovative technology platform to find novel small molecules inhibiting USP15. Dr.

Interplay between Inflammation and Sternness in Cancer Cells: The Role of Toll-Like Receptor Signaling

Joan Seoane , Director of Translational Research at the Vall d'Hebron Institute of Oncology (VHIO) and ICREA Research Professor identified USP15 as a critical protein in cancer which, thanks to its molecular characteristics, shows enormous therapeutic promise.

USP15 promotes tumor progression by activating the TGFa pathway.

Seoane's team has unmasked the USP15 enzyme as activator of the TGFa chain reaction.

USP15 acts by controlling and correcting the TGFa activity in the same way that a thermostat regulates temperature.
