FoxP4 (Forkhead box protein P4; also FKHLA) is a 70-80 kDa member of the winged helix transcription factor gene family, FoxP subfamily of proteins. It is a transcriptional repressor that is strongly expressed in embryonic gut and lung epithelium, and in neurons both pre-and postnatally. Postnatally, it is found in cerebellar Purkinje cells. During development, it is found in hippocampal hilus, proliferating cells of the ventricular zone, and neurons of the basolateral nucleus of the amygdala. Human FoxP4 is 680 amino acids (aa) in length. It contains a large poly-Gln region (aa 65-219), a C2H2 Zn-finger domain (aa 307-332), a Leu-zipper dimerization motift (aa 349-370) and a forkhead DNA binding domain (aa 467-559). Phosphorylation occurs at Ser360. FoxP4 forms homodimers, and heterodimers with FoxP1 and FoxP2; it does not bind CTBP1. One potential splice form shows a deletion of aa 384-395. Over aa 549-680, human and mouse FoxP4 share 89% aa identity.

Scientific Data Images for Human FoxP4 Antibody
Detection of Human FoxP4 by Western Blot.
Western blot shows lysates of COS‑7 African green monkey SV40 transformed kidney fibroblast-like cell line either mock transfected, transfected with human FoxP1, transfected with human FoxP2, transfected with human FoxP3, or transfected with human FoxP4. PVDF membrane was probed with 1:1000 dilution of Sheep Anti-Human FoxP4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6854) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody. For additional reference, the membrane was co-probed with an Anti-Actin Antibody. A specific band was detected for FoxP4 at approximately 75 kDa and Actin at approximately 43 kDa (as indicated). This experiment was conducted under reducing conditions.Image courtesy of Dr. Alison Banham, Ms. Linden Lyne, and Dr. Paola Bignone, The University of Oxford, Oxford, UK.Applications for Human FoxP4 Antibody
