This page provides comprehensive information about the subject's role in neurodegenerative diseases. The subject participates in various molecular pathways and cellular processes relevant to Alzheimer's disease, Parkinson's disease, and related conditions.
RAD51 is a 339-amino acid protein that forms a helical filament on single-stranded DNA (ssDNA). The protein has an N-terminal domain involved in filament formation, a core ATPase domain, and a C-terminal DNA-binding domain. RAD51 forms nucleoprotein filaments essential for homologous recombination.
RAD51 is the central recombinase mediating homologous recombination (HR) repair of double-strand DNA breaks. RAD51 binds to 3' overhangs of resected DNA ends, forming nucleoprotein filaments that search for homologous sequences and catalyze strand invasion. HR is essential for maintaining genomic stability in post-mitotic neurons 1.
RAD51 deficiency causes a recessive form of ALS characterized by progressive motor neuron degeneration. Impaired DNA repair leads to accumulation of DNA damage, genomic instability, and neuronal death 2.
RAD51 dysfunction contributes to mitochondrial DNA damage in dopaminergic neurons, increasing vulnerability to Parkinson's disease. RAD51 activators are being explored as potential neuroprotective agents 3.
The study of Rad51 Protein has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
