Antibody Panel to Members of the Forkhead Box (FOX) Transscription Factor Family - FocusOn 124

Introduction

FOX transcription factors are characterized by the FOX domain, which is an ~100-amino-acid monomeric DNA binding domain. The three-dimensional structure of FOX domain consists of two W1 and W2 loops (or wings) and three helices. Due to the butterfly-like appearance, FOX domain is also known as ‘winged-helix’ domain.

Forkhead-box (FOX) gene family consists of at least 43 members, including FOXA1, FOXA2, FOXA3, FOXB1, FOXC1, FOXC2, FOXD1, FOXD2, FOXD3, FOXD4, FOXD5 (FOXD4L1), FOXD6 (FOXD4L3), FOXE1, FOXE2, FOXE3, FOXF1, FOXF2, FOXG1 (FOXG1B), FOXH1, FOXI1, FOXJ1, FOXJ2, FOXJ3, FOXK1, FOXK2, FOXL1, FOXL2, FOXM1, FOXN1, FOXN2 (HTLF), FOXN3 (CHES1), FOXN4, FOXN5 (FOXR1), FOXN6 (FOXR2), FOXO1 (FOXO1A), FOXO2 (FOXO6), FOXO3 (FOXO3A), FOXO4 (MLLT7), FOXP1, FOXP2, FOXP3, FOXP4, and FOXQ1. FOXE3-FOXD2 (1p33), FOXQ1-FOXF2-FOXC1 (6p25.3), and FOXF1-FOXC2-FOXL1 (16q24.1) loci are FOX gene clusters within the human genome. Members of FOX subfamilies A-G, I-L and Q were grouped into class 1 FOX proteins, while members of FOX subfamilies H and M-P were grouped into class 2 FOX proteins. C-terminal basic region within the FOX domain was the common feature of class 1 FOX proteins. FOXH1 and FOXO1 mRNAs are expressed in human embryonic stem (ES) cells. FOXC1, FOXC2, FOXE1, FOXE3, FOXL2, FOXN1, FOXP2 and FOXP3 genes are mutated in human congenital disorders. FOXA1 gene is amplified and over-expressed in esophageal and lung cancer. FOXM1 gene is up-regulated in pancreatic cancer and basal cell carcinoma due to the transcriptional regulation by Sonic Hedgehog (SHH) pathway. FOXO1 gene is fused to PAX3 or PAX7 genes in rhabdomyosarcoma. FOXO3 and FOXO4 genes are fused to MLL gene in hematological malignancies. Deregulation of FOX family genes leads to congenital disorders, diabetes mellitus, or carcinogenesis.

The forkhead (Fox) gene family comprises a diverse group of winged-helix transcription factors that play important roles in development, metabolism, cancer and aging. Recently, several forkhead genes have been demonstrated to play critical roles in lymphocyte development and effector function, including FoxP3 in the development of regulatory T cells, FoxJ1 and FoxO3a in the regulation of CD4+ T cell tolerance, and FoxN1 in thymic development. Roles for other forkhead genes have also been proposed, including FoxP1 in macrophage differentiation, FoxP1 in natural killer cell effector function and FoxD2 in T cell activation. Thus, forkhead genes promise insight into the mechanisms of immunoregulation in several immune cell lineages, and their dysregulation likely contributes to the pathogenesis of several immunological disorders, suggesting that their study will lead to the development of novel therapeutic agents.
