PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a forkhead (FH, winged helix) domain
	two loops-wings on the C-terminal side of helix-turn-helix homeo domain

HOMOLOGY

interspecies

homolog to Drosophila homeo fork head DNA binding domain

Homologene

FAMILY

HNF-3 forkhead family of transcriptional activator

CATEGORY

transcription factor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,nucleus,chromatin/chromosome

basic FUNCTION	embryonic transcriptional regulator of pulmonary genes
	playing a crucial role in lung and intrinsic pulmonary vascular development (Stankiewicz 2009)
	with FOXL1, are mediators of the Hh (endoderm) to mesoderm signaling pathway (Madison 2009)
	mesenchymal target of hedgehog signaling, known to regulate mesenchymal-epithelial interactions during lung development
	potential tumor suppressor gene with an essential role in preventing DNA rereplication to maintain genomic stability, which is frequently inactivated in breast cancer through the epigenetic mechanism
	is required for normal development of gastrointestinal smooth muscle
	FOXF1 and SRF synergistically activate the telokin promoter and FOXF1 promotes SRF-myocardin binding
	in smooth muscle cells is required for the development and normal physiological function of the gastrointestinal tract
	is not only important for visceral smooth muscle development but also for maintaining expression of contractile proteins in adult gastrointestinal smooth muscle tissues

INTERACTION

DNA

binding

RNA

small molecule

protein	HOXA13 directly regulates TEK and FOXF1 in the placental labyrinth endothelia
	directly binds to and activates the telokin (MYLK) promoter
	also directly binds to serum response factor (SRF) and myocardin-related transcription factors (MRTFs)
	FOXF1 and FOXQ1 directly bind to distinct regions of MYOCD
