  Function in Host
Involved in translation termination in response to thetermination codons UAA, UAG and UGA. Stimulates theactivity of ETF1. Involved in regulation of mammaliancell growth. Component of the transient SURF complexwhich recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Required for SHFL-mediated translation terminationwhich inhibits programmed ribosomal frameshifting (-1PRF) of mRNA fromviruses and cellular genes. [1-3]
