Lrpap1 Gene Summary [Mouse]

Enables low-density lipoprotein particle receptor binding activity. Predicted to be involved in several processes, including amyloid-beta clearance by transcytosis; negative regulation of amyloid-beta clearance; and negative regulation of very-low-density lipoprotein particle clearance. Predicted to be located in Golgi apparatus; endoplasmic reticulum; and vesicle. Predicted to be active in several cellular components, including cis-Golgi network; endoplasmic reticulum-Golgi intermediate compartment; and rough endoplasmic reticulum lumen. Is expressed in several structures, including central nervous system; egg cylinder; foregut; genitourinary system; and lung. Human ortholog(s) of this gene implicated in Alzheimer's disease; dementia; myocardial infarction; and myopia. Orthologous to human LRPAP1 (LDL receptor related protein associated protein 1).

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 Lrpap1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
  • Alpha-2-macroglobulin RAP, C-terminal domain
  • receptor antagonist activity
  • Alpha-2-macroglobulin RAP, N-terminal domain
  • enzyme binding
  • receptor agonist activity
  • central domain
  • beta-amyloid binding
  • protein binding
  • low-density lipoprotein receptor binding
  • receptor binding
  • Receptor-associated protein (RAP)
