Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation,
Specificity / Sensitivity
OTUD7B/Cezanne-1 Antibody recognizes endogenous levels of total OTUD7B/Cezanne-1 protein. This antibody does not cross-react with either OTUD7A or OTUD7C/A20
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human OTUD7B/Cezanne-1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from various cell lines using OTUD7B/Cezanne-1 Antibody.
Western blot analysis of extracts from 293T cells, mock transfected (-) or transfected with a construct expressing Myc/DDK-tagged full-length human OTUD7B protein (hOTUD7B-Myc/DDK; +), using OTUD7B/Cezanne-1 Antibody.
Protein ubiquitination and deubiquitination are reversible processes catalyzed by ubiquitinating enzymes and deubiquitinating enzymes respectively (1,2). Deubiquitinating enzymes (DUBS) are categorized into five subfamilies based on catalytic domain structure: USP, UCH, OTU, MJD, and JAMM. The deubiquitinase cellular zinc-finger anti-NF-κB (Cezanne-1, OTUD7B) is an OTU family deubiquitinase that contains amino-terminal catalytic and ubiquitin-associated (UBA) domains, and a carboxy-terminal A20-like zinc finger (A20-ZnF) that is involved in ubiquitin binding (3,4). Research studies demonstrate that Cezanne-1 negatively regulates canonical NF-κB signaling induced by TNF receptor signaling by removing K63-linked ubiquitin chains from the RIP1 adaptor protein (5,6). Cezanne-1 negatively regulates non-canonical NF-κB signaling through the deubiquitination and stabilization of the TRAF3 signal transduction protein (7). Additional research suggests that Cezanne-1 is a breast cancer oncogene as the corresponding OTUD7B gene is amplified in a subset of breast cancers and enhances EGFR signaling through a mechanism involving receptor stabilization (8).
