Acts upstream of or within cellular protein localization. Located in membrane. Is expressed in several structures, including alimentary system; central nervous system; heart; sensory organ; and skeleton. Used to study megalencephalic leukoencephalopathy with subcortical cysts. Human ortholog(s) of this gene implicated in megalencephalic leukoencephalopathy with subcortical cysts 2A and megalencephalic leukoencephalopathy with subcortical cysts 2B. Orthologous to human HEPACAM (hepatic and glial cell adhesion molecule). [provided by Alliance of Genome Resources, Apr 2022]
