What's a GeneRIF?

Rpn1 and Rpn2 coordinate ubiquitin processing factors at proteasome.
Title: Rpn1 and Rpn2 coordinate ubiquitin processing factors at proteasome.
Comparison of the full-length Rpn1 and Rpn2 with the truncated proteins showed molecules similar in size and shape, indicating that their terminal regions are flexible and thus smeared to invisibility in the averaged images.
Title: Electron microscopic evidence in support of alpha-solenoid models of proteasomal subunits Rpn1 and Rpn2.
Rpn2 interfaces with the 20S, whereas Rpn1 sits atop Rpn2, serving as a docking site for a substrate-recruitment factor. The 19S ATPases encircle the Rpn1-Rpn2 stack, covering the remainder of the 20S surface.
Title: The central unit within the 19S regulatory particle of the proteasome.
