該基因編碼一種含有多個蛋白質相互作用域的蛋白質，包括錨蛋白樣重復序列、卷曲螺旋結構域和atp/gtp結合基序。編碼蛋白與神經元組織中的α-突觸核蛋白相互作用，可能在胞漿內含物的形成和神經變性中起作用。這個基因的突變與帕金森氏癥有關。選擇性剪接導致多個轉錄變體。
This gene encodes a protein containing several protein-protein interaction domains, including ankyrin-like repeats, a coiled-coil domain, and an ATP/GTP-binding motif. The encoded protein interacts with alpha-synuclein in neuronal tissue and may play a role in the formation of cytoplasmic inclusions and neurodegeneration. A mutation in this gene has been associated with Parkinson's disease. Alternative splicing results in multiple transcript variants.
