**Background of PAK7 Protein**
PAK7 (p21-activated kinase 7), a member of the PAK family of serine/threonine kinases, plays critical roles in regulating cell signaling, cytoskeletal dynamics, and neuronal development. Belonging to group II PAKs (alongside PAK4. PAK5. and PAK6), PAK7 differs structurally from group I PAKs by lacking an autoinhibitory domain and containing a C-terminal kinase domain and a PH-like motif. It is activated by binding to Rho GTPases like Cdc42 and Rac, though its regulatory mechanisms remain less defined compared to other PAKs.
Functionally, PAK7 is implicated in cell motility, survival, proliferation, and cytoskeletal reorganization. In the nervous system, it influences neuronal morphogenesis, axon guidance, and synaptic plasticity, contributing to brain development and cognitive functions. Dysregulation of PAK7 has been linked to pathological conditions, including cancer—where overexpression often correlates with tumor invasiveness and metastasis—and neurological disorders like Alzheimer’s disease and intellectual disabilities. Emerging studies also highlight its role in embryonic development, particularly in cardiac and skeletal systems.
PAK7’s dual roles in physiological and disease contexts make it a compelling target for therapeutic research. Ongoing studies aim to elucidate its signaling networks and explore kinase inhibitors or modulators for treating cancer and neurodegenerative conditions. However, its complex interactions and tissue-specific functions warrant further investigation to fully harness its clinical potential.
