Product details

What are the advantages of a recombinant monoclonal antibody?
This product is a recombinant monoclonal antibody, which offers several advantages including:

- High batch-to-batch consistency and reproducibility
- Improved sensitivity and specificity
- Long-term security of supply
- Animal-free batch production

For more information, read more on recombinant antibodies.

Conjugation ready
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

Supplementary information

The eRF3/GSPT1 protein also known as GSPT1 plays an important role in translation termination. It works with eRF1 to release the newly synthesized polypeptide chain from the ribosome. GSPT1 is a GTPase of approximately 69 kDa commonly expressed in human tissues with higher concentrations found in proliferating cells such as those in the bone marrow and lymphoid tissues. It implements essential tasks in protein synthesis regulation by facilitating proper translation termination.

Biological function summary

GSPT1 is involved in processes beyond translation termination. It associates with complexes that regulate mRNA translation and stability. As part of the eRF3 pathway GSPT1 interacts with various translation and post-translation machinery. Its molecular function extends to include potential interactions with lncRNAs such as lnc-SNHG16 indicating a role in cellular processes like cell growth and division. GSPT1's interaction network suggests that it performs multifunction in cell regulation.

Pathways

GSPT1 integrates into the translation termination pathway tightly linking with the mRNA surveillance pathway. This protein is essential for efficient recognition and release of stop codons. In these pathways it collaborates with proteins such as eRF1 to regulate mRNA stability and translation accuracy. These interactions ensure the fidelity of protein biosynthesis and proper cellular function.

The role of GSPT1 extends to cancer and neurodegenerative diseases. Overexpression or mutations of GSPT1 links to various cancers including gastric and colorectal cancers where it affects cell proliferation pathways. The GSPT1-Myc axis appears to contribute significantly to oncogenesis acting with proteins like c-Myc to promote tumorigenesis. Additionally disruptions in GSPT1 function could associate with neurological disorders where translation termination processes malfunction although these aspects require further study.

Target data

GTPase component of the eRF1-eRF3-GTP ternary complex, a ternary complex that mediates translation termination in response to the termination codons UAA, UAG and UGA (PubMed : 15987998, PubMed : 19417105, PubMed : 2511002, PubMed : 27863242). GSPT1/ERF3A mediates ETF1/ERF1 delivery to stop codons : The eRF1-eRF3-GTP complex binds to a stop codon in the ribosomal A-site (PubMed : 27863242). GTP hydrolysis by GSPT1/ERF3A induces a conformational change that leads to its dissociation, permitting ETF1/ERF1 to accommodate fully in the A-site (PubMed : 16777602, 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 : 24486019). Required for SHFL-mediated translation termination which inhibits programmed ribosomal frameshifting (-1PRF) of mRNA from viruses and cellular genes (PubMed : 30682371).
