Systematic name YBR272C
Gene name HSM3
Aliases
Feature type ORF, Verified
Coordinates Chr II:747803..746361
Primary SGDID S000000476


Description of YBR272C: Proteasome-interacting protein involved in the assembly of the base subcomplex of the 19S proteasomal regulatory particle (RP); involved in DNA mismatch repair during slow growth; weak similarity to Msh1p; related to human 19S subunit S5b; structural study suggests Hsm3p is a scaffold protein for Rpt1p-Rpt2p complex formation[1][2][3][4][5][6][7]
