Function

Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Binds to ubiquitinated cargo proteins and is required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies (MVBs). Mediates the association between the ESCRT-0 and ESCRT-I complex. Required for completion of cytokinesis; the function requires CEP55. May be involved in cell growth and differentiation. Acts as a negative growth regulator. Involved in the budding of many viruses through an interaction with viral proteins that contain a late-budding motif P-[ST]-A-P. This interaction is essential for viral particle budding of numerous retroviruses. Required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413). It may also play a role in the extracellular release of microvesicles that differ from the exosomes (PubMed:22315426).

Notes

This goat monoclonal chimeric antibody has been engineered from a RabMAb parent antibody (Anti-TSG101 antibody [EPR7130(B)] ab125011). By necessity, some rabbit sequence is retained as part of the variable domain. When multiplexing with other rabbit-derived antibodies, using cross absorbed Fc-reactive secondary antibodies are recommended.

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

Activity summary

TSG101 also known as Tumor Susceptibility Gene 101 is a protein involved in intracellular trafficking specifically notable within the process of endosomal sorting. It is a component of the ESCRT-I (Endosomal Sorting Complex Required for Transport-I) complex. TSG101 is approximately 46 kDa and is expressed ubiquitously across various tissues. The mechanistic function of TSG101 involves the recognition and ubiquitination of cargo proteins an important step in the formation of multivesicular bodies.

Biological function summary

TSG101 plays a critical role in the sorting and trafficking of proteins destined for lysosomal degradation or recycling back to the plasma membrane. It is an essential part of the ESCRT machinery which also includes other components like VPS37 and VPS28. TSG101 interacts with specific domains and motifs on target proteins facilitating the recognition and recruitment of these proteins into vesicles. Its involvement in membrane budding and scission makes it important for maintaining cellular homeostasis and protein quality control.

Pathways

TSG101 is integrally involved in the ESCRT pathway and is associated with processes like viral budding and cytokinesis. Within these pathways it collaborates with proteins such as ALIX and the ESCRT-II component VPS25 to mediate vesicle formation and facilitate the trafficking of ubiquitinated cargo. The ESCRT pathway is vital in cellular responses such as membrane repair and is important for the life cycle of certain enveloped viruses which utilize host cell machinery for budding.

Associated diseases and disorders

Defects or alterations in TSG101 expression have correlations with tumor progression and neurodegenerative diseases. Disruptions in the function of TSG101 can affect cellular processes potentially contributing to conditions like cancer and Alzheimer's disease. For example the aberrant activity of TSG101 may interact with proteins like Hrs and ubiquitin ligases Mdm2 in the context of oncogenic signaling pathways which can drive tumor growth and metastasis. Understanding these interactions is key to uncovering potential therapeutic targets within these diseases.

Nuclear DNA was labelled with DAPI (shown in blue). The section was then mounted using Dako Fluorescence Mounting Medium®.
    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
    For other IHC staining systems (automated and non-automated), customers should optimize variable parameters such as antigen retrieval conditions, antibody concentrations and incubation times.
