Entrez Gene Summary for LRP8 Gene

  • This gene encodes a member of the low density lipoprotein receptor (LDLR) family. Low density lipoprotein receptors are cell surface proteins that play roles in both signal transduction and receptor-mediated endocytosis of specific ligands for lysosomal degradation. The encoded protein plays a critical role in the migration of neurons during development by mediating Reelin signaling, and also functions as a receptor for the cholesterol transport protein apolipoprotein E. Expression of this gene may be a marker for major depressive disorder. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

GeneCards Summary for LRP8 Gene

LRP8 (Low Density Lipoprotein Receptor-Related Protein 8, Apolipoprotein E Receptor) is a Protein Coding gene. Diseases associated with LRP8 include myocardial infarction, susceptibility to, 1 and myocardial infarction. Among its related pathways are Signaling by GPCR and Disease. GO annotations related to this gene include calcium ion binding and apolipoprotein binding. An important paralog of this gene is LRP1B.

UniProtKB/Swiss-Prot for LRP8 Gene

  • Cell surface receptor for Reelin (RELN) and apolipoprotein E (apoE)-containing ligands. LRP8 participates in transmitting the extracellular Reelin signal to intracellular signaling processes, by binding to DAB1 on its cytoplasmic tail. Reelin acts via both the VLDL receptor (VLDLR) and LRP8 to regulate DAB1 tyrosine phosphorylation and microtubule function in neurons. LRP8 has higher affinity for Reelin than VLDLR. LRP8 is thus a key component of the Reelin pathway which governs neuronal layering of the forebrain during embryonic brain development. Binds the endoplasmic reticulum resident receptor-associated protein (RAP). Binds dimers of beta 2-glycoprotein I and may be involved in the suppression of platelet aggregation in the vasculature. Highly expressed in the initial segment of the epididymis, where it affects the functional expression of clusterin and phospholipid hydroperoxide glutathione peroxidase (PHGPx), two proteins required for sperm maturation. May also function as an endocytic receptor.

Post-translational modifications for LRP8 Gene

  • O-glycosylated. Some alternatively spliced isoforms lack the O-linked sugar domain (By similarity).
  • Tyrosine phosphorylated upon apoE binding.
  • Ubiquitinated by MYLIP leading to degradation.
  • Undergoes sequential, furin and gamma-secretase dependent, proteolytic processing, resulting in the extracellular release of the entire ligand-binding domain as a soluble polypeptide and in the intracellular domain (ICD) release into the cytoplasm. The gamma-secretase-dependent proteolytical processing occurs after the bulk of the extracellular domain has been shed, in a furin-dependent manner, in alternatively spliced isoforms carrying the furin cleavage site. Hypoglycosylation (mainly hypo-O-glycosylation) leads to increased extracellular cleavage, which in turn results in accelerating release of the intracellular domain (ICD) by the gamma-secretase. The resulting receptor fragment is able to inhibit Reelin signaling and in particular the Reelin-induced DAB1 phosphorylation (By similarity).
  • Glycosylation at Thr85, Asn176, Asn441, Asn518, Asn538, Asn772, and Asn807
  • Modification sites at PhosphoSitePlus
