Epsilon-Sarcoglycan is a protein encoded by the SGCE gene that belongs to the sarcoglycan family of transmembrane proteins. While primarily studied in the context of muscular dystrophies, epsilon-sarcoglycan is also expressed in the brain and has been implicated in neurodegenerative diseases, particularly Myoclonus-Dystonia syndrome and Parkinson's disease [1].

Introduction
Epsilon-Sarcoglycan is a single-pass transmembrane protein that is part of the dystrophin-associated glycoprotein complex (DGC). In muscle, it forms a complex with other sarcoglycans (alpha, beta, gamma, delta) to provide structural stability to the sarcolemma. In the brain, epsilon-sarcoglycan is expressed in various regions including the cerebellum, basal ganglia, and cerebral [cortex](/brain-regions/cortex), where it is thought to play roles in synaptic function and neuronal signaling [2].
