Interacts with PPP1CA. Localized to the cilia of polarized ependymal cells during development and at the adult stage (PubMed:28194645). Preferentially locates between the peripheral microtubules of the axoneme and the ciliary membrane (PubMed:28194645). Expressed in brain, ovaries and testis (PubMed:15018803). Expressed in the tracheal epithelium and in secondary spermatocytes and spermatids present in the seminiferous tubule (PubMed:28194645). Expressed in ependymal cells lining the ventricular walls of the brain (PubMed:28194645). At E17 expressed in cells of the ventricular wall in the lateral and third ventricle and to cells in the neuronal parenchyma. At PN1, mainly expressed in the walls of the lateral and third ventricles with an apical polarization.
