**Background of Recombinant Human RNF32 Protein**
Recombinant human RNF32 (RING finger protein 32) is a ubiquitously expressed E3 ubiquitin ligase belonging to the RING finger protein family, characterized by a conserved C3HC4-type zinc-binding RING domain. This domain facilitates interaction with E2 ubiquitin-conjugating enzymes, enabling substrate-specific ubiquitination—a post-translational modification critical for regulating protein stability, localization, and activity. RNF32 is implicated in diverse cellular processes, including embryonic development, cell differentiation, and apoptosis. Studies suggest its involvement in neural tube formation and neurogenesis, with knockout models in mice showing developmental defects in the nervous system.
RNF32’s biological role extends to modulating signaling pathways such as Wnt and Notch, which are essential for tissue homeostasis and stem cell maintenance. Dysregulation of RNF32 has been linked to pathologies, including neurodegenerative diseases and cancers, though mechanistic details remain under investigation. The recombinant form of RNF32 is typically produced in mammalian or bacterial expression systems, allowing in vitro studies of its enzymatic activity, substrate binding, and interaction networks. Its application spans basic research exploring ubiquitin-proteasome system dynamics and drug discovery efforts targeting E3 ligases for therapeutic intervention. As an engineered protein, recombinant RNF32 retains functional fidelity, offering a tool to dissect its physiological and pathophysiological roles.
