RPN3/YER021W Summary Help

Standard Name RPN3 1
Systematic Name YER021W
Alias SUN2 2
Feature Type ORF, Verified
Description 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 (2, 3, 4, 5)
