Predicted to enable adrenergic receptor binding activity and identical protein binding activity. Acts upstream of or within several processes, including extracellular matrix organization; mRNA polyadenylation; and regulation of translation. Located in Golgi apparatus and membrane. Is expressed in several structures, including genitourinary system; nervous system; pancreas trunk epithelium; sensory organ; and tooth. Orthologous to human APLP1 (amyloid beta precursor like protein 1). [provided by Alliance of Genome Resources, Apr 2022]
