Detection of Human Tollip by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and LNCaP human prostate cancer cell line. PVDF membrane was probed with 1 µg/mL of Human Tollip Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4678) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Tollip at approximately 30 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 4.

Tollip (Toll-interacting protein) is a 30 kDa, cytoplasmic protein that is involved in IL-1 and Toll receptor signaling. It is classified as an adaptor protein that performs multiple functions. It binds both IRAK and Toll receptors, inhibiting constitutive IL-1 and Toll receptor signaling. It also binds to ubiquinated IL-1 RI, directing it to the endosomal degradation compartment. Human Tollip is 274 amino acids (aa) in length. It contains a C2 Ca++-binding region (aa 54‑154) and a CUE domain (aa 229‑270) that binds ubiquitin. One potential splice form exists that shows a deletion of aa’s 6‑33. Human Tollip is 92% identical to mouse and canine Tollip.
