The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 112 kDa.
Use a concentration of 10 µg/ml.
FunctionActivates ubiquitin by first adenylating with ATP its C-terminal glycine residue and thereafter linking this residue to the side chain of a cysteine residue in E1, yielding an ubiquitin-E1 thioester and free AMP.
Tissue specificityExpressed in a variety of normal and tumor cell types, but is reduced in lung cancer cell lines.
PathwayProtein modification; protein ubiquitination.
Sequence similaritiesBelongs to the ubiquitin-activating E1 family.
