Predicted to be involved in several processes, including regulation of ryanodine-sensitive calcium-release channel activity; skeletal muscle fiber development; and skeletal muscle satellite cell maintenance involved in skeletal muscle regeneration. Predicted to act upstream of or within several processes, including cellular response to caffeine; positive regulation of skeletal muscle cell proliferation; and response to muscle activity involved in regulation of muscle adaptation. Predicted to be active in endoplasmic reticulum membrane. Human ortholog(s) of this gene implicated in congenital fiber-type disproportion and rigid spine muscular dystrophy 1. Orthologous to human SELENON (selenoprotein N). [provided by Alliance of Genome Resources, Apr 2022]
