What's a GeneRIF?

the alpha7 N terminus of 20S proteasome has a role in core particle activation different from that of the alpha3 N terminus, and Fub1 antagonizes a specific function of the alpha7 N terminus
Title: N-terminal α7 deletion of the proteasome 20S core particle substitutes for yeast PI31 function.
Data indicate that the dynamic gate can be opened by allosteric coupling to a tetrahedral transition state at any of the working active centers of proteasome.
Title: A tetrahedral transition state at the active sites of the 20S proteasome is coupled to opening of the alpha-ring channel.
