Lrp8 Gene Summary [Mouse]

Enables several functions, including amyloid-beta binding activity; apolipoprotein binding activity; and reelin receptor activity. Involved in several processes, including nervous system development; reelin-mediated signaling pathway; and regulation of dendrite development. Acts upstream of or within hippocampus development; layer formation in cerebral cortex; and positive regulation of protein kinase activity. Located in cell surface and extracellular space. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynaptic density membrane. 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, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Lrp8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
