Systematic name YER151C
Gene name UBP3
Aliases BLM3
Feature type ORF, Verified
Coordinates Chr V:472424..469686
Primary SGDID S000000953


Description of YER151C: Ubiquitin-specific protease involved in transport and osmotic response; interacts with Bre5p to co-regulate anterograde and retrograde transport between the ER and Golgi; involved in transcription elongation in response to osmostress through phosphorylation at Ser695 by Hog1p; inhibitor of gene silencing; cleaves ubiquitin fusions but not polyubiquitin; also has mRNA binding activity[1][2][3][4][5][6]

blm3-1 is an allele of UBP3 and BLM10 does not act as a suppressor of blm3-1. Further, blm10 null mutants are not sensitive to DNA damaging agents. The original error in cloning Blm10/Blm3 has caused enormous confusion in the proteasome field. [7] [8]
