CELE_C35B1.1, C35B1.1
ubc-1 encodes an E2 ubiquitin-conjugating enzyme that contains a novel 40 amino acid C-terminal tail, and is homologous to Saccharomyces cerevisiae RAD6/UBC2 which is involved in DNA repair; although loss of UBC-1 activity via RNA-mediated interference (RNAi) does not result in any abnormalities, UBC-1 is able to complement the DNA repair defects of a Saccharomyces cerevisiae rad6 null mutant, suggesting that UBC-1 can function in the DNA repair pathway; ubc-1 mRNA is detectable in embryos.

Characterization of C. elegans RING finger protein 1, a binding partner of ubiquitin-conjugating enzyme 1.

Crowe E, Candido EP

In a yeast two-hybrid screen, RING finger protein 1 (RFP-1) and UBR1 were identified as potential binding partners of C. elegans UBC-1, a ubiquitin-conjugating enzyme with a high degree of identity to S. cerevisiae UBC2/RAD6. The interaction of RFP-1 and UBC-1 was confirmed by co-immunoprecipitation experiments. Yeast interaction trap experiments mapped the region of interaction to the basic N-terminal 313 ... [more]
