Description

Pelota (known as DOM34 in yeast) binds Hbs1, which is EF1-alpha-related subfamily GTPase, and is considered to play a crucial role in mRNA surveillance for protein synthesis [PMID: 18022361]. It is involved in No-go decay (NGD) and non-stop decay (NSD) surveillance mechanisms that target mRNAs on which elongation complexes are stalled. Pelota/Hbs1 were shown to promote dissociation of stalled elongation complexes and release of intact peptidyl-tRNA in the presence of the ATP-binding cassette protein ABCE1 [PMID: 21448132]. Pelota is conserved in eukaryotes and archaea [PMID: 20974926].
