GeneID: 51



Names

Common Name: APOL1 Type: Gene
Chromosome: 22 (NC_000022.11) Locus: NG_023228.1 (APOL1)
HUGO Symbol: APOL1 Full Name: apolipoprotein L1
Exons: 7 Introns: 6

Description:
The APOL1 gene encodes a 43.9 kDa protein, which constitutes the apoprotein part of high-density lipoprotein (HDL). Therefore, it plays a role in lipid exchange and transport throughout the body, as well as in reverse cholesterol transport from peripheral cells to the liver. The secreted APOL1 protein circulates exclusively in association with plasma lipoproteins, particularly apoA-I-containing lipoproteins. APOL1 is largely bound to HDL3 particles, which contain two other proteins, apolipoprotein A1 (apoA-I) and haptoglobin-related protein, forming a protein complex that functions as a trypanolytic factor. Following endocytosis of the APOL1-containing HDL by bloodstream-form trypanosomes, APOL1 is targeted to the lysosome where its colicin-like pore-forming activity causes osmotic swelling of the lysosome and ultimately death. Polymorphisms in the APOL1 gene that confer protection against trypanosomiasis were also found to be associated with kidney disease in West Africans. The APOL1 G1/G2 variants were associated with urine albumin concentration, proteinuria, glomerular filtration rate, chronic kidney disease, and end-stage renal disease in cohorts with sickle cell nephropathy.

Synonyms: APOL , APO-L , FSGS4 , APOL-I
