TRIOBP (Trio- and F-actin-Binding Protein) is a cytoskeleton-associated protein crucial for maintaining structural integrity in various tissues, particularly in the inner ear. Encoded by the *TRIOBP* gene on human chromosome 22q13. it exists in multiple splice variants, with TRIOBP-1 (short isoform) and TRIOBP-4 (long isoform) being the most studied. TRIOBP-4 is predominantly expressed in the cochlea, where it stabilizes F-actin bundles within the stereocilia of hair cells, essential for sound transduction. Mutations in *TRIOBP* are linked to autosomal recessive nonsyndromic hearing loss (DFNB28), highlighting its role in auditory function.
Structurally, TRIOBP contains coiled-coil domains and actin-binding regions, enabling it to act as a scaffold for cytoskeletal organization. Beyond the auditory system, TRIOBP interacts with signaling molecules like TRIO, influencing cell adhesion, migration, and neural development. Emerging studies suggest its involvement in neuropsychiatric disorders, including schizophrenia, though mechanisms remain unclear.
Recombinant TRIOBP proteins are used to investigate its molecular interactions, dissect mutation impacts, and model hearing-related pathologies *in vitro*. Research tools include overexpression systems and knockouts to explore its dual roles in cytoskeletal dynamics and disease pathways, offering potential for therapeutic targeting in hearing disorders and beyond.
