**Background of YWHAG Recombinant Protein**
YWHAG (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein gamma), also known as 14-3-3γ, is a member of the highly conserved 14-3-3 protein family. These proteins function as regulatory hubs in eukaryotic cells, modulating signal transduction by binding to phosphorylated serine/threonine residues on client proteins. The 14-3-3γ isoform plays critical roles in diverse cellular processes, including cell cycle regulation, apoptosis, metabolism, and stress responses, by interacting with kinases, phosphatases, transcription factors, and disease-associated targets like CDC25. BAD, and Raf family members.
Recombinant YWHAG protein is engineered *in vitro* using expression systems such as *E. coli* or mammalian cell lines, often fused with tags (e.g., GST, His) to facilitate purification and detection. Its structure features a conserved amphipathic groove that binds phosphorylated motifs, enabling dimerization (homodimers or heterodimers with other 14-3-3 isoforms) essential for scaffolding functions.
This recombinant protein is widely utilized to study 14-3-3γ-mediated interactions *in vitro* (e.g., pull-down assays, co-immunoprecipitation) and serves as a standard in quantitative analyses (e.g., ELISA). It also aids in drug discovery, particularly in screening compounds targeting dysregulated 14-3-3 interactions implicated in cancers, neurodegenerative disorders (e.g., Alzheimer’s), and metabolic diseases. Dysregulation of YWHAG expression or function has been linked to tumor progression and neuronal death, underscoring its therapeutic relevance. By providing a controllable and pure protein source, recombinant YWHAG accelerates mechanistic studies and the development of precision therapies.
