TRIM58 Antibody / Tripartite motif containing protein 58

TRIM58 antibody targets tripartite motif containing protein 58, an E3 ubiquitin ligase encoded by the TRIM58 gene on chromosome 1q44. TRIM58 is a member of the tripartite motif-containing family of proteins, which share a characteristic structure consisting of a RING domain, one or two B-box domains, and a coiled-coil region. This protein family is involved in diverse cellular processes such as protein ubiquitination, innate immunity, cell cycle regulation, and signal transduction. TRIM58, in particular, has been studied for its role in erythropoiesis and red blood cell maturation.TRIM58 functions as an E3 ubiquitin ligase, tagging specific substrate proteins with ubiquitin for degradation by the proteasome. During erythropoiesis, TRIM58 promotes the enucleation of developing erythroblasts, a critical step in red blood cell maturation. It achieves this by targeting proteins involved in cytoskeletal organization and nuclear expulsion. Loss of TRIM58 activity disrupts terminal erythropoiesis and can contribute to anemia-related pathologies.Emerging studies suggest that TRIM58 may also act as a tumor suppressor. Downregulation of TRIM58 has been reported in hepatocellular carcinoma, lung cancer, and colorectal cancer, where it may contribute to uncontrolled proliferation by failing to degrade oncogenic proteins. Restoring TRIM58 expression in cancer models can inhibit growth and promote apoptosis, highlighting the relevance of this protein in oncology research. TRIM58 antibody is therefore a versatile reagent for studying red blood cell development, cancer biology, and ubiquitination pathways.Experimental applications include western blotting, immunocytochemistry, immunoprecipitation, and ELISA. In hematology research, TRIM58 antibody has been used to monitor erythroid differentiation stages, correlating expression levels with enucleation efficiency. In cancer studies, antibodies against TRIM58 help determine expression levels across tumor versus normal tissues, providing insights into diagnostic and therapeutic approaches.By studying TRIM58, researchers gain a deeper understanding of ubiquitin ligase networks and their impact on development and disease. Given its unique role in erythropoiesis and potential tumor suppressor function, TRIM58 remains a protein of growing biomedical interest. The availability of this reagent from NSJ Bioreagents supports both fundamental and translational investigations.
