GTPase component of the Pelota-HBS1L complex, a complex that recognizes stalled ribosomes and triggers the No-Go Decay (NGD) pathway (PubMed:21448132, PubMed:23667253, PubMed:27863242). The Pelota-HBS1L complex recognizes ribosomes stalled at the 3' end of an mRNA and engages stalled ribosomes by destabilizing mRNA in the mRNA channel (PubMed:27863242). Following mRNA extraction from stalled ribosomes by the SKI complex, the Pelota-HBS1L complex promotes recruitment of ABCE1, which drives the disassembly of stalled ribosomes, followed by degradation of damaged mRNAs as part of the NGD pathway (PubMed:21448132, PubMed:32006463). {ECO:0000269|PubMed:21448132, ECO:0000269|PubMed:23667253, ECO:0000269|PubMed:27863242, ECO:0000269|PubMed:32006463}. This is the function of HBS1L (HBS1 like translational GTPase, Ensembl gene identifier ENSG00000112339).
