Enables reelin receptor activity. Involved in dendrite morphogenesis; positive regulation of dendrite development; and reelin-mediated signaling pathway. Acts upstream of or within positive regulation of protein kinase activity and ventral spinal cord development. Located in extracellular space. Is expressed in several structures, including alimentary system; genitourinary system; musculoskeletal system; nervous system; and sensory organ. Used to study age related macular degeneration 1. Human ortholog(s) of this gene implicated in Alzheimer's disease; cerebellar ataxia, mental retardation and dysequlibrium syndrome; and dementia. Orthologous to human VLDLR (very low density lipoprotein receptor). [provided by Alliance of Genome Resources, Apr 2022]
