**Background of Recombinant Human EFR3A Protein**
Recombinant human EFR3A protein is a genetically engineered version of the EFR3 homolog A (EFR3A) protein, a critical regulator of phosphoinositide metabolism in eukaryotic cells. EFR3A, a conserved scaffolding protein, anchors the phosphatidylinositol 4-kinase (PI4K) complex to the plasma membrane, facilitating the synthesis of phosphatidylinositol 4-phosphate (PI4P), a precursor for signaling lipids like PIP2. This process is vital for membrane trafficking, cytoskeletal organization, and cellular signaling.
Structurally, EFR3A contains an N-terminal α-helical region for membrane association and C-terminal domains that interact with PI4KIIIα and other regulatory proteins. Dysregulation of EFR3A is linked to neurological disorders and cancers, underscoring its role in cellular homeostasis.
The recombinant protein is typically expressed in *E. coli* or mammalian systems, purified via affinity chromatography, and used in functional studies, drug screening, and disease mechanism research. Its production enables detailed investigation of EFR3A’s interactions, post-translational modifications, and potential therapeutic targeting in pathologies involving lipid signaling imbalances.
