The function of ENSG00000129654 (FOXJ1, forkhead box J1) is as follows. 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. {ECO:0000250|UniProtKB:Q61660, ECO:0000269|PubMed:31630787}.
