Transcriptional coactivator stimulating NR5A1 and ligand-dependent NR1H3/LXRA and PPARG transcriptional activities. Enhances the DNA-binding activity of ATF1, ATF2, CREB1 and NR5A1. Regulates nitric oxid synthase activity probably by sequestering calmodulin in the cytoplasm. May function in endothelial cells differentiation, hormone-induced cardiomyocytes hypertrophy and lipid metabolism.
Expressed in brain, liver, lung, kidney and heart (at protein level). Ubiquitously expressed. More abundant in heart, pancreas, liver, intestine and adipose tissues.
Contains 1 HTH cro/C1-type DNA-binding domain.
Expressed in fetal tissues. More abundant in kidney.
The IQ motif, which is involved in calmodulin binding, overlaps with the binding domain for nuclear receptors and transcription factors. Its phosphorylation probably allows a switch between the two activities of the protein.
Phosphorylated (by PKA and PKC).
Cytoplasm. Nucleus. Also nuclear upon binding to NR5A1 and treatment of cells with TPA or forskolin.
Detection of EDF1 in Immunoprecipitates of 293T whole cell lysates (1 mg for IP, 20% of IP loaded) using ab174651 at 6 µg/mg lysate for IP (Lane 1). For WB detection ab174651 was used at 1 µg/ml. Lane 2 represents control IgG IP.
