Anti-TRIM23 / Tripartite motif-containing protein 23

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml. TRIM23 antibody detects Tripartite motif-containing protein 23, a multifunctional E3 ubiquitin ligase involved in autophagy, vesicle trafficking, and innate immunity. The UniProt recommended name is Tripartite motif-containing protein 23 (TRIM23). This cytoplasmic protein belongs to the TRIM family, characterized by RING, B-box, and coiled-coil domains mediating protein-protein interactions and ubiquitin ligase activity.Functionally, TRIM23 antibody identifies a 586-amino-acid protein that regulates signaling complexes and autophagy. TRIM23 ubiquitinates and activates TBK1 kinase, promoting antiviral autophagy and interferon responses. It also coordinates endomembrane trafficking by acting as an Arf GAP (GTPase-activating protein), linking vesicular dynamics to immune signaling.The TRIM23 gene is located on chromosome 5q12.3 and is expressed in multiple tissues, with highest levels in brain, lung, and immune cells. Through its dual ubiquitin ligase and Arf GAP activities, TRIM23 integrates membrane trafficking and host defense. It contributes to selective autophagy of pathogens and protein aggregates.Pathologically, altered TRIM23 expression has been associated with neurodegeneration, viral infection, and cancer. In neurons, TRIM23 maintains axonal homeostasis, while in immune cells it regulates autophagic responses. Research using TRIM23 antibody supports studies in innate immunity, autophagy, and vesicle biology.TRIM23 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect E3 ligases and autophagy regulators. NSJ Bioreagents provides TRIM23 antibody reagents optimized for studies in protein ubiquitination, intracellular trafficking, and immune signaling.Structurally, Tripartite motif-containing protein 23 features a RING finger domain for E3 ligase activity, B-box and coiled-coil domains for dimerization, and a C-terminal ARF GAP domain. This antibody supports detailed analysis of TRIM23's regulatory roles in autophagy and innate immune signaling.
