Serum Albumin/ALB Protein, Human (HEK293, His-Avi)

The serum albumin/ALB protein has multiple binding abilities and can bind water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin, and drugs. Its main effects include regulating blood colloid osmotic pressure to achieve homeostasis. Serum Albumin/ALB Protein, Human (HEK293, His-Avi) is the recombinant human-derived Serum Albumin/ALB protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of Serum Albumin/ALB Protein, Human (HEK293, His-Avi) is 585 a.a., with molecular weight of 69-70 kDa.

The Serum Albumin/ALB protein serves a multifaceted role by binding to water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin, and drugs, indicative of its versatile binding capabilities. Its primary function likely revolves around the regulation of the colloidal osmotic pressure of blood, emphasizing its pivotal role in maintaining blood homeostasis. Notably, ALB acts as a major transporter for zinc, binding approximately 80% of all plasma zinc, and also serves as a significant transporter for calcium and magnesium, binding about 45% of circulating calcium and magnesium in plasma. The presence of potential calcium-binding sites suggests its involvement in calcium transport, with a distinct affinity rank order of zinc > calcium > magnesium. Additionally, ALB exhibits an intriguing interaction with the bacterial siderophore enterobactin, inhibiting enterobactin-mediated iron uptake of E. coli and potentially limiting the utilization of iron by enteric bacteria. Furthermore, ALB engages in interactions with FCGRT, regulating its homeostasis, and forms a covalently-linked complex with chromophore-bound alpha-1-microglobulin in plasma, highlighting its diverse roles in molecular interactions and maintaining its functionality in fatty acid binding.
