Predicted to be involved in myoblast fusion; plasma membrane fusion; and positive regulation of skeletal muscle hypertrophy. Predicted to act upstream of or within myoblast fusion involved in skeletal muscle regeneration. Predicted to be located in plasma membrane. Predicted to be integral component of Golgi membrane and integral component of plasma membrane. Human ortholog(s) of this gene implicated in Carey-Fineman-Ziter syndrome. Orthologous to human MYMK (myomaker, myoblast fusion factor). [provided by Alliance of Genome Resources, Apr 2022]
