Entrez ID	174
Gene name	Alpha fetoprotein
Gene symbol	AFP
Synonyms (NCBI Gene)	AFPDFETAHPAFP
Chromosome	4
Chromosome location	4q13.3
Summary	This gene encodes alpha-fetoprotein, a major plasma protein produced by the yolk sac and the liver during fetal life. Alpha-fetoprotein expression in adults is often associated with hepatocarcinoma and with teratoma, and has prognostic value for managing

Protein name

Alpha-fetoprotein (Alpha-1-fetoprotein) (Alpha-fetoglobulin)

Protein function

Binds copper, nickel, and fatty acids as well as, and bilirubin less well than, serum albumin. Only a small percentage (less than 2%) of the human AFP shows estrogen-binding properties.
