Overview:

Alpha-synuclein is a member of the synuclein family which also includes beta- and gamma-synuclein. These proteins are abundantly expressed in the brain and alpha- and beta-synuclein selectively inhibit phospholipase D2 which is a highly conserved protein that is also abundant in neurons, especially presynaptic terminals (1). Alpha-synuclein gene is not a major risk factor in familial Parkinson disease (2). Alpha-synuclein may serve to integrate pre-synaptic signaling and membrane trafficking and Alpha-synuclein peptides are a major component of amyloid plaques in the brains of patients with Alzheimer"s disease.
