Product Description specifically for APOA1 protein

   Manufacturer MyBioSource HUMAN APO A1 apolipoprotein(s) produced for research and bulk diagnostic manufacturing Custom Fills for Human APO A1 Lipoprotein available.

Human APO A1 apolipoprotein: Single polypeptide chain in 245 amino acids with high alpha-helical content, major structurual component of high density lipoproteins, cofactor for lecthin:cholesterol acyltransferase, levels in general are inversely related to risk of coronary artery disease in humans.

Human APO A1 apolipoprotein is isolated by ultracentrifugation and delipidated by organic solvents. Human APO A1 Lipoprotein is purified by ion-exchange chromatography.

Human APO A1 Lipoprotein is soluble in aqueous buffers at low concentrations (<50ug/mL) but due to amphipathic nature, Human APO A1 Lipoprotein will self-associate into oligomers at high concentrations in the absence of chaotrupes (urea, guanidine hydrochloride).

Our Human APO A1 apolipoprotein Sterile Filtered through a.22 micron hydrophilic filter.

Apo-AI comprises ~70% of the protein moiety in HDL. It is a single polypeptide chain consisting of 245 amino acids with glutamic acid as the C-terminal residue and aspartic acid as the N-terminal residue. The molecular mass is reported to be 28.3 kDa. The protein is made up of one major isoform (pI 5.6) and two minor isoforms (pI 5.53 and 5.46). Apo-AI shows a high content of -helix structure. The amphipathic regions in the -helix structure seem to be responsible for lipid binding capacity. In aqueous solution, Apo-AI shows self-association with minor conformation change. Apo-AI activates lecithin-cholesterol (LCAT) acyltransferase, which is responsible for cholesterol esterification in plasma.

 NCBI Summary for APOA1    This gene encodes apolipoprotein A-I, which is the major protein component of high density lipoprotein (HDL) in plasma. The protein promotes cholesterol efflux from tissues to the liver for excretion, and it is a cofactor for lecithin cholesterolacyltransferase (LCAT) which is responsible for the formation of most plasma cholesteryl esters. This gene is closely linked with two other apolipoprotein genes on chromosome 11. Defects in this gene are associated with HDL deficiencies, including Tangier disease, and with systemic non-neuropathic amyloidosis. [provided by RefSeq, Jul 2008]
 UniProt Comments for APOA1    Function: Participates in the reverse transport of cholesterol from tissues to the liver for excretion by promoting cholesterol efflux from tissues and by acting as a cofactor for the lecithin cholesterol acyltransferase (LCAT). As part of the SPAP complex, activates spermatozoa motility. Ref.20

Subunit structure: Interacts with APOA1BP and CLU. Component of a sperm activating protein complex (SPAP), consisting of APOA1, an immunoglobulin heavy chain, an immunoglobulin light chain and albumin. Interacts with NDRG1. Ref.25 Ref.31 Ref.34

Subcellular location: Secreted.

Tissue specificity: Major protein of plasma HDL, also found in chylomicrons. Synthesized in the liver and small intestine. The oxidized form at Met-110 and Met-136 is increased in individuals with increased risk for coronary artery disease, such as in carrier of the eNOSa/b genotype and exposure to cigarette smoking. It is also present in increased levels in aortic lesions relative to native ApoA-I and increased levels are seen with increasing severity of disease. Ref.32 Ref.35

Post-translational modification: Palmitoylated. Ref.28Met-110 and Met-136 are oxidized to methionine sulfoxides.Phosphorylation sites are present in the extracelllular medium.

Involvement in disease: Defects in APOA1 are a cause of high density lipoprotein deficiency type 2 (HDLD2) [

MIM:604091]; also known as familial hypoalphalipoproteinemia (FHA). Inheritance is autosomal dominant. Ref.39 Ref.40Defects in APOA1 are a cause of the low HDL levels observed in high density lipoprotein deficiency type 1 (HDLD1) [

MIM:205400]; also known as analphalipoproteinemia or Tangier disease (TGD). HDLD1 is a recessive disorder characterized by the absence of plasma HDL, accumulation of cholesteryl esters, premature coronary artery disease, hepatosplenomegaly, recurrent peripheral neuropathy and progressive muscle wasting and weakness. In HDLD1 patients, ApoA-I fails to associate with HDL probably because of the faulty conversion of pro-ApoA-I molecules into mature chains, either due to a defect in the converting enzyme activity or a specific structural defect in Tangier ApoA-I. Ref.39 Ref.40Note=A mutation in APOA1 is the cause of amyloid polyneuropathy-nephropathy Iowa type (AMYLIOWA); also known as amyloidosis van Allen type or familial amyloid polyneuropathy type III. AMYLIOWA is a hereditary generalized amyloidosis due to deposition of amyloid mainly constituted by apolipoprotein A1. The clinical picture is dominated by neuropathy in the early stages of the disease and nephropathy late in the course. Death is due in most cases to renal amyloidosis. Severe peptic ulcer disease can occurr in some and hearing loss is frequent. Cataracts is present in several, but vitreous opacities are not observed. Ref.39 Ref.40 Ref.45 Ref.46Defects in APOA1 are a cause of amyloidosis type 8 (AMYL8) [

MIM:105200]; also known as systemic non-neuropathic amyloidosis or Ostertag-type amyloidosis. AMYL8 is a hereditary generalized amyloidosis due to deposition of apolipoprotein A1, fibrinogen and lysozyme amyloids. Viscera are particularly affected. There is no involvement of the nervous system. Clinical features include renal amyloidosis resulting in nephrotic syndrome, arterial hypertension, hepatosplenomegaly, cholestasis, petechial skin rash. Ref.39 Ref.40 Ref.48

Sequence similarities: Belongs to the apolipoprotein A1/A4/E family.

Mass spectrometry: Molecular mass is 28081 Da from positions 25 - 267. Determined by ESI. Without methionine sulfoxide. Ref.32Molecular mass is 28098 Da from positions 25 - 267. Determined by ESI. With 1 methionine sulfoxide, oxidation at Met-110. Ref.32Molecular mass is 28095 Da from positions 25 - 267. Determined by ESI. With 1 methionine sulfoxide, oxidation at Met-136. Ref.32Molecular mass is 28114 Da from positions 25 - 267. Determined by ESI. With 2 methionine sulfoxides, oxidation at Met-110 and Met-136. Ref.32
