Western blot analysis of extracts from MCF-7 (lane 2(20μg), Raji (lane 3(20μg), Hela (lane 4(20μg), HepG2 (lane 5(20μg) using RF1 Antibody（HY-P84428). Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80993, 1/10,000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse IgG-HRP Secondary Antibody (HY-P8004 ,1/10,000) was used for 1 hour at room temperature.

Proteins were transferred to a NC membrane and blocked with 5% Skim milk in TBST for 2 hour at room temperature. The primary antibody ( 1/1000) and Loading control antibody (GAPDH，20035, 1/1000) was used in 5% Skim milk in TBST at 4°C overnight. Goat Anti-Mouse IgG-HRP Secondary Antibody (1/10,000) was used for 1 hour at room temperature.

Then stained with the primary antibody at 1/400 dilution overnight at 4℃.Alexa Fluor® 488 Goat Anti-mouse IgG H&L (invitrogen A11001) was used as the secondary antibody at 1/1,000 dilution for 45 minutes at room temperature. Mouse IgG Isotype Control (Invitrogen 14-4714-B2, gray) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (red).

Background

Function：Component of the eRF1-eRF3-GTP ternary complex, a ternary complex that mediates translation termination in response to the termination codons (PubMed:10676813, PubMed:16777602, PubMed:24486019, PubMed:26245381, PubMed:27863242, PubMed:36638793, PubMed:7990965). The eRF1-eRF3-GTP complex binds to a stop codon in the ribosomal A-site (PubMed:26245381, PubMed:27863242, PubMed:36638793). ETF1/ERF1 is responsible for stop codon recognition and inducing hydrolysis of peptidyl-tRNA (PubMed:26245381, PubMed:27863242, PubMed:36638793). Following GTP hydrolysis, eRF3 (GSPT1/ERF3A or GSPT2/ERF3B) dissociates, permitting ETF1/eRF1 to accommodate fully in the A-site and mediate hydrolysis of peptidyl-tRNA (PubMed:10676813, PubMed:16777602, PubMed:26245381, PubMed:27863242). Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons (PubMed:19417104). Required for SHFL-mediated translation termination which inhibits programmed ribosomal frameshifting (-1PRF) of mRNA from viruses and cellular genes (PubMed:30682371)

Subcellular Localization：Cytoplasm

Isoforms & Post-Translational Modification：P62495 has 2 isomers: P62495-1: 49031 Da (predicted); P62495-2: 45463 Da (predicted).
Methylated at Gln-185 by N6AMT1;Hydroxylation at Lys-63 by JMJD4 promotes its translational termination efficiency;Ubiquitinated at Lys-279 via 'Lys-6'-linked polyubiquitin chains by RNF14 and RNF25 in response to ribosome collisions (ribosome stalling), leading to its degradation by the proteasome and rescue of stalled ribosomes

Subunit：Component of the eRF1-eRF3-GTP ternary complex, composed of ETF1/ERF1 and eRF3 (GSPT1/ERF3A or GSPT2/ERF3B) and GTP (PubMed:19417105, PubMed:27863242). Component of the transient SURF (SMG1-UPF1-eRF1-eRF3) complex (PubMed:19417104). Interacts with JMJD4 (PubMed:24486019). The ETF1-GSPT1 complex interacts with JMJD4 (PubMed:24486019)
