**Recombinant human INPP5E protein** is a purified, biologically active form of the inositol polyphosphate 5-phosphatase enzyme encoded by the *INPP5E* gene. INPP5E functions as a phosphoinositide phosphatase, hydrolyzing phosphatidylinositol (4.5)-bisphosphate [PI(4.5)P2] and inositol 1.4.5-trisphosphate [I(1.4.5)P3] to regulate phosphoinositide signaling pathways. This enzyme plays a critical role in primary cilia maintenance, cellular membrane trafficking, and signaling processes, particularly in ciliary biology and Hedgehog (Hh) signaling. Mutations in *INPP5E* are linked to ciliopathies such as Joubert syndrome, a neurodevelopmental disorder characterized by cerebellar and brainstem malformations, intellectual disability, and retinal degeneration. Recombinant INPP5E protein is typically produced using heterologous expression systems (e.g., *E. coli* or mammalian cells) to ensure proper folding and enzymatic activity. Researchers utilize this protein to study its substrate specificity, interaction partners, and mechanisms underlying ciliary dysfunction in disease models. Additionally, it serves as a tool for high-throughput screening of therapeutic compounds targeting INPP5E-related disorders. The recombinant form often includes affinity tags (e.g., His-tag) for purification and detection, with validated activity assays confirming its catalytic function. Its applications extend to elucidating phosphoinositide metabolism dynamics and developing potential gene therapies or enzyme replacement strategies for ciliopathies.
