Anti-FOXJ1 antibodies are used in the immunodetection of the protein forkhead box J1. In humans, the canonical protein has a reported length of 421 amino acid residues and a mass of 45.2 kDa. Its subcellular localization is in the nucleus. It is notably expressed in the nasopharynx, fallopian tube, endometrium, and bronchus. A member of the FOXJ1 protein family, FOXJ1 is reported to be a transcription factor specifically required for the formation of motile cilia. The FOXJ1 marker can be used to identify Ciliated Epithelial Cells, Airway Submucosal Gland Ciliated Duct Cells, Airway Deuterosomal Cells, Bronchus Ciliated Cells, and Lung Ciliated Cells.* Synonyms for this target antigen include FKHL13, HFH-4, HFH4, forkhead box protein J1, fork head homologue 4, and CILD43. FOXJ1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species.
