Synphilin-1 (SNCAIP), a cytoplasmic protein encoded by the SNCAIP gene, is best known for its interaction with α-synuclein, a key player in Parkinson’s disease (PD) pathogenesis. Discovered as an α-synuclein-interacting partner, Synphilin-1 is enriched in Lewy bodies—protein aggregates characteristic of PD and other synucleinopathies. Structurally, it contains multiple domains, including an ubiquitin-like domain, facilitating interactions with proteins involved in ubiquitination and autophagy pathways.
Functionally, Synphilin-1 modulates α-synuclein aggregation, cytotoxicity, and degradation. It acts as a molecular scaffold, promoting the formation of inclusion bodies, potentially as a cytoprotective mechanism to sequester toxic protein species. However, its role remains controversial, as both protective and pathogenic effects have been reported depending on cellular context.
SNCAIP is implicated in PD through genetic and pathological studies. While mutations are rare, its interaction with α-synuclein links it to sporadic PD. Animal models demonstrate that co-expression of both proteins accelerates neurodegeneration. Additionally, Synphilin-1 interacts with parkin, an E3 ubiquitin ligase associated with autosomal recessive PD, suggesting involvement in ubiquitin-proteasome system dysfunction.
Beyond PD, Synphilin-1 intersects with pathways regulating apoptosis, protein homeostasis, and mitochondrial function, highlighting its multifaceted role. Current research focuses on unraveling its precise mechanisms in disease and exploring therapeutic strategies targeting α-synuclein-Synphilin-1 interactions or downstream pathways. Understanding Synphilin-1 biology could provide insights into synucleinopathy mechanisms and potential intervention points.
