Synaptojanin 2 (SYNJ2) is a member of the synaptojanin family of polyphosphoinositide phosphatases, which play crucial roles in regulating membrane dynamics and cellular signaling. It is encoded by the *SYNJ2* gene and primarily hydrolyzes phosphatidylinositol 4.5-bisphosphate (PI(4.5)P2) and phosphatidylinositol 3.4.5-trisphosphate (PI(3.4.5)P3), lipid molecules involved in vesicle trafficking, cytoskeletal reorganization, and signal transduction. Structurally, SYNJ2 contains an N-terminal Sac1 domain for phosphoinositide binding and a central catalytic 5-phosphatase domain, followed by a proline-rich region that mediates protein-protein interactions. Unlike its neuronal-specific paralog SYNJ1. SYNJ2 is ubiquitously expressed and implicated in diverse cellular processes, including clathrin-mediated endocytosis, cell migration, and autophagy. Studies highlight its role in cancer progression, where elevated SYNJ2 expression correlates with metastasis and poor prognosis, possibly by promoting invadopodia formation and extracellular matrix degradation. Additionally, SYNJ2 has been linked to neurological disorders, such as Alzheimer’s disease, through its interaction with amyloid precursor protein (APP). Recent research also explores its involvement in mitochondrial dynamics and apoptosis regulation. Despite progress, the precise molecular mechanisms and context-dependent functions of SYNJ2 remain under investigation, making it a focal point for understanding cellular homeostasis and disease pathogenesis. Targeting SYNJ2 has emerged as a potential therapeutic strategy for cancers and neurodegenerative conditions.
