ZFYVE gene family

Reviewed November 2008

What are the ZFYVE genes?

Genes in the ZFYVE family provide instructions for making proteins that contain a short region called an FYVE zinc finger. This region includes a specific pattern of protein building blocks (amino acids) and two charged atoms of zinc (zinc ions). FYVE zinc fingers direct the proteins that contain them to various compartments within the cell by attaching (binding) to a substance on the surface of these compartments called phosphatidylinositol-3-phosphate (PI3P).

The FYVE zinc finger was named after the initials of the first four proteins that were found to contain this region: Fab1, YOTB, Vac1, and EEA1. There are now at least 60 proteins that are known to contain an FYVE zinc finger.

Which genes are included in the ZFYVE gene family?

The HUGO Gene Nomenclature Committee (HGNC) provides a list of genes in the ZFYVE family (http://www.genenames.org/genefamily/zfyve.php).

Genetics Home Reference summarizes the normal function and health implications of these members of the ZFYVE gene family: FGD1 and FGD4.

What conditions are related to genes in the ZFYVE gene family?

Genetics Home Reference includes these conditions related to genes in the ZFYVE gene family:

Aarskog-Scott syndrome
Charcot-Marie-Tooth disease
