Syncoilin is a muscle-specific intermediate filament, first isolated as a binding partner to α-dystrobrevin, as determined by a yeast two-hybrid assay.[1]
Later, a yeast two-hybrid method was used to demonstrate that syncoilin is a binding partner of desmin.[2] These binding partners suggest that syncoilin acts as a mechanical "linker" between the sarcomere Z-disk (where desmin is localized) and the dystrophin-associated protein complex (where α-dystrobrevin is localized). However, the specific in vivo functions of syncoilin have not yet been determined.
Abnormally high levels of syncoilin have been shown to be a characteristic of neuromuscular wasting diseases, such as desminopathy[3] and muscular dystrophy.[4] Therefore, syncoilin is being explored as a promising marker of neuromuscular disease.
