Recombinant human RNF208 (Ring Finger Protein 208) is a ubiquitin-protein ligase belonging to the RING finger family, characterized by a conserved C3H2C3-type zinc-binding RING domain that facilitates interaction with E2 ubiquitin-conjugating enzymes. This protein plays a role in the ubiquitination process, a post-translational modification critical for regulating protein degradation, cellular signaling, and stress responses. Though its biological functions remain understudied compared to other RING family members, RNF208 is hypothesized to participate in pathways related to DNA repair, cell cycle control, and immune regulation. Its expression has been detected in various tissues, suggesting broad physiological relevance.
Research on recombinant RNF208 primarily focuses on elucidating its substrate specificity, enzymatic mechanisms, and involvement in disease contexts. For instance, studies explore its potential link to cancer progression, neurodegenerative disorders, or viral infections due to the central role of ubiquitination in these processes. The recombinant form is typically produced in eukaryotic systems (e.g., HEK293 cells) to ensure proper folding and post-translational modifications. Purification often involves affinity chromatography tags for experimental applications, such as in vitro ubiquitination assays or interactome analyses. Despite emerging interest, RNF208's full functional landscape and therapeutic potential remain areas of active investigation, necessitating further structural and functional studies to define its role in cellular homeostasis and pathology.
