Summary: This gene encodes a highly conserved protein involved in the preassembly of dynein arm complexes which power cilia. These complexes are found in some cilia and are assembled in the cytoplasm prior to transport for cilia formation. Mutations in the human gene have been associated with primary ciliary dyskinesia.

What's a GeneRIF?

These findings support studies indicating that hypomorphic mutations of human DNAAF2 can result in ciliary dyskinesia and identify Dnaaf2 as an essential component of cilia function in vivo.
Title: A null allele of Dnaaf2 displays embryonic lethality and mimics human ciliary dyskinesia.
Observation of cilia orientation based on basal foot directions revealed that ciliary motility was not required in the alignment of airway cilia, whereas a strong requirement was observed in brain ependymal cells.
Title: The establishment of rotational polarity in the airway and ependymal cilia: analysis with a novel cilium motility mutant mouse.
Ktu/PF13 is one of the long-sought proteins involved in pre-assembly of dynein arm complexes in the cytoplasm before intraflagellar transport loads them for the ciliary compartment
Title: Ktu/PF13 is required for cytoplasmic pre-assembly of axonemal dyneins.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
