Anti-Toll-interacting protein Tollip Antibody Picoband® Fluoro488 Conjugated

TOLLIP (TOLL-Interacting Protein), is an inhibitory adaptor protein that in humans is encoded by the TOLLIP gene. Lo et al. (2009) stated that the TOLLIP gene maps to chromosome 11. The mouse gene maps to chromosome 7. By Western blot analysis of embryonic kidney cells, Burns et al. (2000) confirmed the binding of TOLLIP to IL1RAP, to a complex of IL1RAP-IL1R1, and to IL18R. Burns et al. (2000) proposed that IL1B stimulation induces aggregation of IL1Rs, recruitment of MYD88 followed by TOLLIP-IRAK complexes, and the phosphorylation of IRAK by MYD88. This leads to the dissociation of TOLLIP from IRAK, which can then transmit the IL1-induced signals.

Abundantly expressed in thymocytes and lymphocytes. Detected in lymphocyte-rich tissues such as thymus, colon, intestine, and spleen. Also found in the prostate.

Component of the signaling pathway of IL-1 and Toll-like receptors. Inhibits cell activation by microbial products. Recruits IRAK1 to the IL-1 receptor complex. Inhibits IRAK1 phosphorylation and kinase activity (PubMed:11751856) . Connects the ubiquitin pathway to autophagy by functioning as a ubiquitin- ATG8 family adapter and thus mediating autophagic clearance of ubiquitin conjugates. The TOLLIP-dependent selective autophagy pathway plays an important role in clearance of cytotoxic polyQ proteins aggregates (PubMed:25042851) . .
