Baculoviral IAP repeat-containing protein 7 (280-289)

Baculoviral IAP repeat-containing protein 7 (280-289) is a synthetic peptide fragment derived from a specific region of the BIRC7 protein, also known as Livin. As a member of the inhibitor of apoptosis protein (IAP) family, BIRC7 plays a pivotal role in modulating cell death pathways, particularly through its baculoviral IAP repeat (BIR) domains. The 280-289 amino acid segment represents a defined epitope within the protein, making it valuable for dissecting the molecular interactions and regulatory mechanisms associated with apoptosis inhibition. Researchers leverage such peptides to gain insight into protein-protein interactions, post-translational modifications, and the structural determinants underlying IAP function.

Epitope mapping: The 280-289 peptide sequence serves as a precise tool for epitope mapping studies aimed at identifying antibody binding sites within the BIRC7 protein. By utilizing this defined fragment, researchers can generate or validate monoclonal and polyclonal antibodies with specificity for the targeted region, facilitating the development of highly selective immunoassays and improving the accuracy of protein detection in complex biological samples.

Protein-protein interaction analysis: This peptide fragment enables in vitro investigations into the binding affinities and interaction partners of the BIRC7 protein, particularly those that recognize or are regulated by the BIR domain. By incorporating the 280-289 sequence into binding assays or pull-down experiments, scientists can elucidate the molecular interfaces involved in apoptosis regulation, ubiquitination, or other signaling pathways in which BIRC7 participates.

Peptide-based inhibitor screening: The defined structure of the 280-289 peptide allows it to be employed as a model substrate or competitive ligand in high-throughput screening platforms. Researchers can use the peptide to identify small molecules, peptides, or protein domains that interact with or modulate the activity of BIRC7, supporting the discovery of novel modulators of apoptotic signaling for basic research purposes.

Structural and conformational studies: The synthetic peptide corresponding to residues 280-289 offers a simplified system for detailed biophysical and structural analyses, such as nuclear magnetic resonance (NMR) spectroscopy or circular dichroism (CD) studies. These investigations provide insights into the secondary structure propensity of the region, its potential for post-translational modifications, and its role in the overall folding and function of the full-length protein.

Immunogenicity research: The 280-289 sequence can be used as an immunogen for raising region-specific antibodies or for studying T-cell epitope recognition in immunological assays. Its defined length and sequence make it suitable for evaluating immune responses to BIRC7-derived peptides, which is valuable in fundamental studies of antigen presentation and immune surveillance mechanisms related to apoptosis regulators.
