Beta-synuclein is a protein that in humans is encoded by the SNCB gene. [5] [6] [7]
The protein encoded by this gene is highly homologous to alpha-synuclein. These proteins are abundantly expressed in the brain and putatively inhibit phospholipase D2 selectively. The encoded protein, which may play a role in neuronal plasticity, is abundant in neurofibrillary lesions of patients with Alzheimer's disease. This protein has been shown to be highly expressed in the substantia nigra of the brain, a region of neuronal degeneration in patients with Parkinson's disease; however, no direct relation to Parkinson's disease has been established. Two transcript variants encoding the same protein have been found for this gene. [7]
Beta-synuclein is a synuclein protein found primarily in brain tissue and is seen mainly in presynaptic terminals. Beta-synuclein is predominantly expressed in the neocortex, hippocampus, striatum, thalamus, and cerebellum. It is not found in Lewy bodies, but it is associated with hippocampal pathology in PD and DLB. [8]
Beta-synuclein is suggested to be an inhibitor of alpha-synuclein aggregation, which occurs in neurodegenerative diseases such as Parkinson's disease. Thus, beta-synuclein may protect the central nervous system from the neurotoxic effects of alpha-synuclein and provide a novel treatment of neurodegenerative disorders. [9] [10]
