Enables identical protein binding activity. Predicted to be involved in several processes, including plasma membrane repair; proteasome-mediated ubiquitin-dependent protein catabolic process; and protein homooligomerization. Predicted to act upstream of or within negative regulation of insulin receptor signaling pathway; negative regulation of insulin-like growth factor receptor signaling pathway; and negative regulation of myotube differentiation. Predicted to be located in cytoplasmic vesicle membrane. Predicted to be active in cytoplasm and sarcolemma. [provided by Alliance of Genome Resources, Jul 2025]
