● HGNC ( 1092 or FOXL2

Gene locus:


Protein name:

Forkhead box L2

Protein Size:

376 amino acids; about 39 kDa

Function :

This gene encodes a transcription factor with a fork-head DNA-binding domain. FOXL2 is a critical factor essential for ovary differentiation and maintenance, and repression of the genetic program for somatic testis determination. Prevents trans-differentiation of ovary to testis through transcriptional repression of the Sertoli cell-promoting gene SOX9 and may play a role in ovarian development and function.

Cancer-related alterations:

Somatic mutations, consisting in substitutions only, are observed in about 25% of ovarian cancers. More than 95% of mutations target amino acid 134.
