Description

Pho4 Regulatory Protein (Sacch Cerev) is a highly purified protein derived from *Saccharomyces cerevisiae* (baker's yeast). This specific protein plays a critical role in the regulation of phosphate metabolism and gene expression within yeast systems. It is an essential reagent for molecular biology research, particularly in studies of transcriptional regulation, signal transduction pathways, and yeast genetics. Researchers in biotechnology, pharmaceuticals, and academic institutions require this high-quality protein for consistent and reproducible experimental results.

Application

• Transcriptional Regulation Studies: Used as a key component in in vitro and in vivo assays to investigate the mechanisms of gene expression control.
• Biochemical Assay Development: Serves as a standard or active ingredient in developing assays for phosphatase activity and phosphate signaling pathways.
• Protein-Protein Interaction Analysis: Employed in pull-down assays, co-immunoprecipitation, and yeast two-hybrid screens to map interaction networks.
• Enzyme Kinetics & Characterization: Provides a purified substrate or regulatory factor for detailed enzymatic studies.
• Academic & Industrial Research: Supports fundamental and applied research in molecular biology, systems biology, and metabolic engineering.
• Diagnostic Reagent Component: Potential use as a purified antigen or standard in the development of research-grade diagnostic kits.
