Recombinant human PSCD4 (Pleckstrin Homology, Sec7. and Coiled-coil Domains-containing protein 4) is a multifunctional protein implicated in cellular signaling and membrane trafficking processes. Structurally, it contains distinct domains: a pleckstrin homology (PH) domain that binds phosphoinositides for membrane targeting, a Sec7 domain with guanine nucleotide exchange factor (GEF) activity to activate small GTPases like ARF proteins, and coiled-coil motifs facilitating protein-protein interactions. PSCD4 is broadly expressed in tissues, particularly in the brain, and plays roles in cytoskeletal remodeling, vesicle transport, and cell proliferation. Dysregulation of PSCD4 has been linked to cancers, neurological disorders, and immune dysfunction, with studies suggesting its involvement in oncogenic pathways (e.g., PI3K/AKT) and synaptic plasticity. Recombinant PSCD4 is typically produced via bacterial or mammalian expression systems, purified using affinity chromatography, and utilized to study its molecular mechanisms, interactions, and therapeutic potential. Its recombinant form enables functional assays, structural analysis, and drug screening, offering insights into disease mechanisms and targeted intervention strategies. Research continues to explore its dual roles as a signaling hub and potential biomarker in pathological conditions.
