This review highlights TPPP3's involvement in neuronal functions and potential as a therapeutic target for neurodegenerative diseases, suggesting broad implications in treatment strategies.
Tubulin polymerization-promoting protein family member 3 (TPPP3) is a neuronal-specific protein involved in cytoskeletal stability, axonal maintenance, and neuronal survival. Dysregulation of TPPP3 is implicated in neurodegenerative diseases such as Parkinson's disease and diabetic retinopathy. Unlike TPPP1, which is oligodendrocyte-specific, TPPP3 was reported to primarily promote neuronal regeneration and serve as a therapeutic target for neurodegenerative diseases such as Parkinson's disease and glaucoma. Beyond the nervous system, TPPP3 has been linked to oncogenesis and tissue regeneration, suggesting potential roles in tumor suppression and wound healing. This review summarizes neuronal functions of TPPP3, therapeutic opportunities, and future research directions. Understanding the molecular mechanisms underlying function of TPPP3 could provide valuable insights into its therapeutic applications in neuroprotection.
