Anti-Sortilin-related receptor SORL1 Antibody

Sortilin-related receptor; Low-density lipoprotein receptor relative with 11 ligand-binding repeats; LDLR relative with 11 ligand-binding repeats; LR11; SorLA-1; Sorting protein-related receptor containing LDLR class A repeats; SorLA; SORL1; C11orf32;

Expressed mainly in brain, where it is most abundant in the cerebellum, cerebral cortex and the occipital pole; low expression in the putamen and the thalamus. Expression is significantly reduced in the frontal cortex of patients suffering from Alzheimer disease. According to PubMed:9157966, found in spinal cord, testis, liver, kidney and pancreas with detectable levels in placenta, lung and heart. According to PubMed:8940146, expressed in the prostate, ovary, thyroid and spleen, but not found in kidney, liver, lung, skeletal muscle, bone marrow and adrenals.

The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE) .

Likely to be a multifunctional endocytic receptor, that may be implicated in the uptake of lipoproteins and of proteases. Binds LDL, the major cholesterol-carrying lipoprotein of plasma, and transports it into cells by endocytosis. Binds the receptor- associated protein (RAP) . Could play a role in cell-cell interaction. Involved in APP trafficking to and from the Golgi apparatus. It probably acts as a sorting receptor that protects APP from trafficking to late endosome and from processing into amyloid beta, thereby reducing the burden of amyloidogenic peptide formation. Involved in the regulation of smooth muscle cells migration, probably through PLAUR binding and decreased internalization.
