Enables several functions, including amyloid-beta binding activity; apolipoprotein binding activity; and reelin receptor activity. Involved in several processes, including nervous system development; positive regulation of CREB transcription factor activity; and regulation of dendrite development. Acts upstream of or within central nervous system development and positive regulation of protein kinase activity. Located in cell surface and extracellular space. Is expressed in nervous system and retina layer. Human ortholog(s) of this gene implicated in Alzheimer's disease; coronary artery disease; dementia; myocardial infarction; and schizophrenia. Orthologous to human LRP8 (LDL receptor related protein 8). [provided by Alliance of Genome Resources, Apr 2022]
