HBS1/YKR084C Summary Help

Standard Name HBS1 1
Systematic Name YKR084C
Feature Type ORF, Verified
Description GTPase with similarity to translation release factors; together with binding partner Dom34p, facilitates ribosomal subunit dissociation and peptidyl-tRNA release when translation is stalled; genetically implicated in mRNA no-go decay; HBS1 has a paralog, SKI7, that arose from the whole genome duplication (1, 2, 3, 4, 5, 6, 7)
Name Description Hsp70 subfamily B Suppressor 1
