Prolow-density lipoprotein receptor-related protein 1 (Q91ZX7)

Uniprot ID Q91ZX7
Protein Name Prolow-density lipoprotein receptor-related protein 1
Gene Name Lrp1
Species Mus musculus (Mouse)
Signal peptide(a) Y Secretome P(b) 0.0
Function Endocytic receptor involved in endocytosis and in phagocytosis of apoptotic cells. Required for early embryonic development (PubMed:1423604). Involved in cellular lipid homeostasis. Involved in the plasma clearance of chylomicron remnants and activated LRPAP1 (alpha 2-macroglobulin), as well as the local metabolism of complexes between plasminogen activators and their endogenous inhibitors. May modulate cellular events, such as APP metabolism, kinase-dependent intracellular signaling, neuronal calcium signaling as well as neurotransmission. Acts as an alpha-2-macroglobulin receptor (By similarity). .(Microbial infection) Functions as a receptor for Vibrio cholerae cholix toxin and for Pseudomonas aeruginosa exotoxin A. {ECO:0000269|PubMed:1618748, ECO:0000269|PubMed:18276581}.
