Alpha-fetoprotein

特許 権利維持 Alpha-fetoprotein (AFP, α-fetoprotein; also sometimes called alpha-1-fetoprotein, alpha-fetoglobulin, or alpha fetal protein) is a protein[1][2] that in humans is encoded by the AFP gene.[3][4] The AFP gene is located on the q arm of chromosome 4 (4q25). AFP is a major plasma protein produced by the yolk sac and the liver during fetal development. It is thought to be the fetal form of serum albumin. AFP binds to copper, nickel, fatty acids and bilirubin[4] and is found in monomeric, dimeric and trimeric forms.
