Summary

Expression: HEK293
Binding assay: Yes (SPR)
Amino Acid Range: Asp25-Leu609

SKU: 4223parent Categories: proteins, Recombinant proteins Tag: active proteins

Weight	1 lbs
Dimensions	9 × 5 × 2 in
accession	P02768
express system	HEK293
product tag	C-His-Avi
purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
background	Human serum albumin (HSA), the most prominent protein in plasma, binds different classes of ligands at multiple sites. HSA provides a depot for many compounds, affects pharmacokinetics of many drugs, holds some ligands in a strained orientation providing their metabolic modification, renders potential toxins harmless transporting them to disposal sites, accounts for most of the antioxidant capacity of human serum, and acts as a NO-carrier.
molecular weight	The protein has a predicted MW of 69.4 kDa. Due to glycosylation, the protein migrates to 69-70 kDa based on Tris-Bis PAGE result.
available size	100 µg, 500 µg
endotoxin	Less than 1EU per μg by the LAL method.

Protein names Albumin
Gene names ALB,ALB GIG20 GIG42 PRO0903 PRO1708 PRO2044 PRO2619 PRO2675 UNQ696/PRO1341
Protein family ALB/AFP/VDB family
Mass 9606Da
Function Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017).
Subellular location Secreted.
Tissues Plasma.
Structure Interacts with FCGRT; this interaction regulates ALB homeostasis (PubMed:28330995). Interacts with TASOR (By similarity). In plasma, occurs in a covalently-linked complex with chromophore-bound alpha-1-microglobulin with molar ratio 1:2 and 1:1; this interaction does not prevent fatty acid binding to ALB.
Post-translational modification Kenitra variant is partially O-glycosylated at Thr-620. It has two new disulfide bonds Cys-600 to Cys-602 and Cys-601 to Cys-606.; Glycated in diabetic patients.; Phosphorylated by FAM20C in the extracellular medium.; Acetylated on Lys-223 by acetylsalicylic acid.
