Disease relevance of USP33

In particular we identified two novel genes not previously reported: endomucin (EMCN) and ubiquitin specific protease 33 (USP33) that appear to be over-expressed in B-ALL relative to their expression in T-ALL [1].

High impact information on USP33

D2 interaction with VDU1 and VDU2, a closely related deubiquitinase, was confirmed in mammalian cells [2].
A novel protein named VHL-interacting deubiquitinating enzyme 1 (VDU1) was identified as being able to directly interact with pVHL in vitro and in vivo [3].

Other interactions of USP33

Targeted degradation of VDU1 by pVHL could be crucial for regulating the ubiquitin-proteasome degradation pathway [3].
Based on human and mouse cDNA sequences, VDU1 and VDU2 are identical in approximately 59% of the amino acids with strong homology in the N-terminus and C-terminus and a weaker similarity in the middle region [4].
