靶點詳情

  • 最新研究進展:
    ALB,全稱為白蛋白,是一種重要的血漿蛋白。最近的研究表明,ALB在多種疾病的發生和發展中發揮著重要作用,包括肝病、腎病和心血管疾病等。ALB參與了細胞內外的物質轉運、細胞凋亡和免疫反應等生物學過程。
  • 功能:
    Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs. Its main function is the regulation of the colloidal osmotic pressure of blood. Major zinc transporter in plasma, typically binds about 80% of all plasma zinc. Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (Probable). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner. The shared binding site between zinc and calcium at residue Asp-272 suggests a crosstalk between zinc and calcium transport in the blood (Probable). The rank order of affinity is zinc > calcium > magnesium (Probable). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli. Does not prevent iron uptake by the bacterial siderophore aerobactin.

    23. new insights on bovine serum albumin self-assembly process PMID: 21303653
    24. Data indicate that CD spectroscopy of the HSA and BSA released in solution after desorption from the matrices shows that, while both proteins partially regain their helical structure, they show a distinct behaviour in their tertiary structure. PMID: 20692819
