1-19 3.41e-06

Forkhead (FH) domain found in Forkhead box (FOX) family of transcription factors and similar proteins; The FOX family comprises diverse tissue- and cell type-specific transcription factors with an evolutionary conserved "Forkhead (FH)" or "winged helix" DNA-binding domain. FH is named for the Drosophila fork head protein, a transcription factor which promotes terminal rather than segmental development. The structure of the FH domain contains 2 flexible loops or "wings" in the C-terminal region, hence the term winged helix. FOX transcription factors recognize the core sequence 5'-(A/C)AA(C/T)A-3'. They participate in a variety of cellular processes, such as cell cycle progression, proliferation, differentiation, migration, metabolism, and DNA damage response. Their expression can be regulated by multiple factors, and they can act as co-activators and/or transcriptional repressors. Fifty FOX-encoding genes in humans have been categorized into 19 subfamilies based on protein sequence homology (FOXA to FOXS).

Forkhead (FH) domain found in Forkhead box protein O3 (FOXO3); FOXO3, also called AF6q21 protein or Forkhead in rhabdomyosarcoma-like 1 (FKHRL1), is a transcriptional activator which triggers apoptosis in the absence of survival factors, including neuronal cell death upon oxidative stress. It recognizes and binds to the DNA sequence 5'-[AG]TAAA[TC]A-3'. The FH domain is a winged helix DNA-binding domain. All FOXOs bind to the consensus sequence 5'-GTAAACAA-3', known as the DAF-16 family member-binding element, which includes the core sequence 5'-(A/C)AA(C/T)A-3' recognized by all FOX family members.
