Smt3 Antibody (E-1) is a mouse monoclonal IgG1 kappa light chain antibody that detects the Smt3 protein of Saccharomyces cerevisiae origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). anti-Smt3 antibody (E-1) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Smt3, a member of the ubiquitin-like protein family, plays a crucial role in cellular processes by regulating protein stability and localization through sumoylation, which maintains cellular homeostasis. This post-translational modification involves covalent attachment of Smt3 to target proteins, influencing function, interactions, and degradation pathways. Smt3 modifies proteins essential for DNA repair, cell cycle regulation, and stress responses, maintaining cellular integrity and function. Smt3 also interacts with several key proteins, including Ubc9, necessary for conjugation to substrates, and Skp1, which links cell cycle regulators to ubiquitin proteolysis machinery, highlighting Smt3′s integral role in cellular signaling and regulation.
