Description

Toll-Interacting Protein Antibody / TOLLIP Polyclonal Antibody targets Toll-interacting protein (TOLLIP), an intracellular adaptor involved in innate immune signaling, membrane trafficking, and protein homeostasis. TOLLIP helps coordinate interactions between signaling complexes and intracellular membrane compartments, contributing to the regulation of inflammatory responses and the processing of ubiquitinated proteins. Its functions connect receptor-mediated signaling with mechanisms that control protein localization and degradation.

TOLLIP was originally identified as a regulatory component of interleukin-1 receptor signaling. It associates with interleukin-1 receptor-associated kinase 1 (IRAK1) and participates in mechanisms that influence downstream activation of inflammatory pathways. TOLLIP also regulates signaling initiated by Toll-like receptors, which recognize microbial components and other molecular signals associated with cellular stress. Through these interactions, TOLLIP can contribute to the attenuation of excessive inflammatory signaling and the maintenance of immune homeostasis.

The protein contains a central C2 domain and a C-terminal CUE domain that support distinct molecular interactions. The C2 domain contributes to phospholipid binding and membrane association, while the CUE domain recognizes ubiquitin and ubiquitinated substrates. These structural features enable TOLLIP to associate with intracellular membranes and proteins undergoing sorting or degradation. Its interactions with phosphoinositides and ubiquitinated cargo are particularly relevant to endosomal organization and the regulation of protein trafficking.

Beyond inflammatory signaling, TOLLIP participates in endosomal transport and selective autophagy-related processes. It has been implicated in the handling of ubiquitinated proteins and the delivery of selected cargo toward lysosomal degradation. These activities connect TOLLIP with cellular proteostasis, a network of processes responsible for maintaining protein quality and preventing the accumulation of damaged or improperly processed proteins.

TOLLIP function has been investigated in inflammatory diseases, pulmonary disorders, and conditions involving altered innate immune responses. Genetic variation within the TOLLIP locus has been associated with differences in disease susceptibility and clinical outcomes, although the underlying mechanisms vary among conditions. Its involvement in both inflammatory regulation and intracellular trafficking makes TOLLIP relevant to understanding how cells coordinate immune signaling with protein turnover.

Toll-Interacting Protein Antibody supports research into TOLLIP-associated signaling complexes, ubiquitin-dependent protein sorting, and the mechanisms linking inflammatory regulation with endosomal and lysosomal function.

Application Notes

The stated application concentrations are suggested starting amounts. Titration of the Toll-Interacting Protein Antibody / TOLLIP Polyclonal Antibody may be required due to differences in protocols and secondary/substrate sensitivity.

Immunogen

An amino acid sequence from the C-terminus of human Toll-Interacting Protein (NAQPRCSEEDLKAIQDMFPN) was used as the immunogen for this Tollip antibody.

Storage

After reconstitution, the Tollip antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
