Transcription factor specifically required for the formation of motile cilia (PubMed:31630787). Acts by activating transcription of genes that mediate assembly of motile cilia, such as CFAP157. Binds the DNA consensus sequences 5'-HWDTGTTTGTTTA-3' or 5'-KTTTGTTGTTKTW-3' (where H is not G, W is A or T, D is not C, and K is G or T). Activates the transcription of a variety of ciliary proteins in the developing brain and lung. Testis, oviduct, lung and brain cortex. Expressed in developing lung, kidney and central nervous system. Disease susceptibility may be associated with variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. Belongs to the FOXJ1 family.
