Protein attributes

Sequence length	837 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Required for cytoplasmic pre-assembly of axonemal dyneins, thereby playing a central role in motility in cilia and flagella. Involved in pre-assembly of dynein arm complexes in the cytoplasm before intraflagellar transport loads them for the ciliary compartment.
Subunit structure	Interacts with DNAI2 and HSPA1A By similarity.
Subcellular location	Cytoplasm. Note: Localizes in the apical cytoplasm around the gamma-tubulin-positive pericentriolar region, not in the cilia. Ref.1
Involvement in disease	Primary ciliary dyskinesia 10 (CILD10) [MIM:612518]: A disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia; reduced fertility is often observed in male patients due to abnormalities of sperm tails. Half of the patients exhibit randomization of left-right body asymmetry and situs inversus, due to dysfunction of monocilia at the embryonic node. Primary ciliary dyskinesia associated with situs inversus is referred to as Kartagener syndrome. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.1
Sequence similarities	Belongs to the PIH1 family. Kintoun subfamily.
Sequence caution	The sequence BAA91684.1 differs from that shown. Reason: Erroneous initiation. The sequence CAD66572.1 differs from that shown. Reason: Erroneous initiation.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q9NVR5-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q9NVR5-2)

The sequence of this isoform differs from the canonical sequence as follows:
     622-669: Missing.

Note: May be due to exon skipping.
