Is predicted to encode a protein with the following domains: Ankyrin repeats (3 copies); Ankyrin repeat-containing domain superfamily; Ankyrin repeats (many copies); Ankyrin repeat; and Domain of unknown function DUF3447. Is an ortholog of C. elegans nphp-2. In C. elegans, nphp-2 is involved in protein localization to ciliary inversin compartment.
