Tyrosine phosphorylation of the intracellular domain of LRP1 serves as a molecular switch to regulate cellular cholesterol homeostasis through nuclear hormone receptor-mediated regulation of the cellular cholesterol exporter ABCA1.
Leukemia-Related Protein 16 (LRP16), a member of the macro domain family, plays a crucial role in orchestrating genotoxicity-initiated NF-κB signaling in the colon and the pathophysiological relevance of NF-κB activation induced by LRP16 in colonic cell survival/recovery from extrinsic DNA damage.
Phosphorylation of the Wnt receptor LRP6 directly inhibits glycogen synthase kinase-3 by acting as a pseudosubstrate that stabilizes an active conformation of the enzyme, identical to autoinhibition by phosphorylation of its N terminus.
In oligodendrocyte progenitor cells, lipid metabolism and peroxisome biogenesis are regulated by the low-density lipoprotein related-receptor-1, and if disrupted, impair proper white matter development and adult repair.
Proteins implicated in Alzheimer’s disease, including amyloid precursor protein and ApoE receptors, interact with each other and with a signalling molecule called agrin to influence the development of the neuromuscular junction.
Lrp4 mutant mice display profound deficits in cognitive tasks that assess learning and memory with disruptions in the subcellular organization of synaptic inputs and synaptic plasticity in the hippocampus.
