Lrp1 Gene Summary [Rat]
Enables coreceptor activity; protease binding activity; and protein serine/threonine kinase binding activity. Involved in several processes, including positive regulation of cell migration; positive regulation of transport; and regulation of neuron projection development. Located in several cellular components, including axonal growth cone; cytoplasmic vesicle; and neuronal cell body. Used to study diabetes mellitus. Biomarker of Alzheimer's disease; prostate carcinoma in situ; and sciatic neuropathy. Human ortholog(s) of this gene implicated in Alzheimer's disease; keratosis pilaris atrophicans; myocardial infarction; and sciatic neuropathy. Orthologous to human LRP1 (LDL receptor related protein 1). [provided by Alliance of Genome Resources, Apr 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 rat Lrp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
