What's a GeneRIF?

Data show that the availability of Rpn11 is important for maintaining adequate levels of intact proteasomes, as its depletion caused growth and proteolytic defects in rpn3.
Title: A proteasome assembly defect in rpn3 mutants is associated with Rpn11 instability and increased sensitivity to stress.

Preferred Names: proteasome regulatory particle lid subunit RPN3

NP_010938.1

Essential non-ATPase regulatory subunit of the 26S proteasome lid; similar to the p58 subunit of the human 26S proteasome; temperature-sensitive alleles cause metaphase arrest, suggesting a role for the proteasome in cell cycle control
