AFX protein belongs to the forkhead protein family. It is highly homologous to the human FKHR protein, the gene of which is disrupted by the t(2;13)(q35;q14), a chromosome rearrangement characteristic of alveolar rhabdomyosarcomas. AFX contains three putative phosphorylation motif sites for protein kinase B (PKB), Thr32, Ser197, and Ser262, and it is proposed that phosphorylated AFX stays in the cytosol and is imported to the nucleus through dephosphorylation to induce target gene expression. Nuclear expression of AFX results in the suppression of various responses to hypoxia, including decreased vascular endothelial growth factor, glucose transporter 1, and erythropoietin expression. Human AFX gene is localized to chromosomal region Xq13.1.
