Function
Forkhead box protein P1 is a protein that in humans is encoded by the FOXP1 gene. FOXP1 is necessary for the proper development of the brain, heart, and lung in mammals. It is a member of the large FOX family of transcription factors. This gene belongs to subfamily P of the forkhead box (FOX) transcription factor family. Forkhead box transcription factors play important roles in the regulation of tissue- and cell type-specific gene transcription during both development and adulthood. Forkhead box P1 protein contains both DNA-binding- and protein-protein binding-domains. This gene may act as a tumor suppressor as it is lost in several tumor types and maps to a chromosomal region (3p14.1) reported to contain a tumor suppressor gene(s). Foxp1 is a transcription factor; specifically it is a transcriptional repressor. Fox genes are part of a forkhead DNA-binding domain family. This domain binds to sequences in promoters and enhancers of many genes. Foxp1 regulates a variety of important aspects of development including tissue development of: the lungs, brain, thymus and heart. In the heart Foxp1 has 3 vital roles, these include the regulation of cardiac myocyte maturation and proliferation, outflow tract separation of the pulmonary artery and aorta, and expression of Sox4 in cushions and myocardium. Foxp1 is also an important gene in muscle development of the esophagus and esophageal epithelium. Foxp1 is also an important regulator of lung airway morphogenesis. Foxp1 knockout embryos display severe defects in cardiac morphogenesis. A few of these defects include myocyte maturation and proliferation defects that cause a thin ventricular myocardial compact zone, non-separation of the pulmonary artery and aorta, and cardiomyocyte proliferation increase and defective differentiation. These defects, caused by Foxp1 inactivation, lead to fetal death. Disruptions of FoxP1 have been identified in very rare human patients and – similarly to FoxP2 - lead to cognitive dysfunction, including intellectual disability and autism spectrum disorder, together with language impairment.

Immunohistochemical analysis of paraffin-embedded rat brain tissue using anti-FoxP1 antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) (high pressure) for 2 minutes. The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ER1901-26, 1/50) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Flow cytometric analysis of FoxP1 was done on MCF-7 cells. The cells were fixed, permeabilized and stained with the primary antibody (ER1901-26, 1/50) (red). After incubation of the primary antibody at room temperature for an hour, the cells were stained with a Alexa Fluor 488-conjugated Goat anti-Rabbit IgG Secondary antibody at 1/1000 dilution for 30 minutes.Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
