Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; low-density lipoprotein particle receptor binding activity; and signaling receptor activator activity. Involved in negative regulation of blood circulation; positive regulation of endothelin production; and positive regulation of tumor necrosis factor production. Acts upstream of or within several processes, including cellular metal ion homeostasis; nervous system development; and regulation of cellular protein metabolic process. Located in several cellular components, including cytoplasmic vesicle; cytoskeleton; and neuromuscular junction. Is integral component of membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; neurogenic placode; and sensory organ. Used to study Alzheimer's disease. Human ortholog(s) of this gene implicated in APP-related cerebral amyloid angiopathy; Alzheimer's disease; Alzheimer's disease 1; cognitive disorder; and visual epilepsy. Orthologous to human APP (amyloid beta precursor protein). [provided by Alliance of Genome Resources, Apr 2022]
