CC -!- FUNCTION: Directs the termination of nascent peptide synthesis
CC (translation) in response to the termination codons UAA, UAG and UGA.
CC Component of the transient SURF complex which recruits UPF1 to stalled
CC ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs
CC containing premature stop codons. Required for SHFL-mediated
CC translation termination which inhibits programmed ribosomal
CC frameshifting (-1PRF) of mRNA from viruses and cellular genes.
CC {ECO:0000250|UniProtKB:P62495}.
CC -!- SUBUNIT: Heterodimer of two subunits, one of which binds GTP (By
CC similarity). Component of the transient SURF (SMG1-UPF1-eRF1-eRF3)
CC complex (By similarity). Interacts with JMJD4 (By similarity). The
CC ETF1-GSPT1 complex interacts with JMJD4 (By similarity).
CC {ECO:0000250|UniProtKB:P62495}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P62495}.
CC -!- PTM: Hydroxylation at Lys-63 by JMJD4 promotes its translational
CC termination efficiency. {ECO:0000305|PubMed:24486019}.
CC -!- PTM: Methylated at Gln-185 by N6AMT1. {ECO:0000250|UniProtKB:P62495}.
CC -!- SIMILARITY: Belongs to the eukaryotic release factor 1 family.
CC {ECO:0000305}.
