  • Function

    May play a role in the regulation of cilium length. Stabilizes microtubules at low temperature.
  • Tissue specificity

    Widely expressed, with highest levels in testis. Expressed in mature spermatozoa (at protein level).
  • Sequence similarities

    Belongs to the FAM154 family.
  • Developmental stage

    In retinal pigment epithelium (RPE1) cell line, after 24 hours of serum starvation to stimulate primary cilium production, present at the mother and daughter basal bodies. At early time points of ciliogenesis, not detected in the axoneme. At later time points, expressed along the axoneme, with increasing levels as maturation of the cilium proceeds.
  • Domain

    The Mn regions are involved in microtubule-binding and stabilization at low temperature. They are required and sufficient for cilium targeting.
    The N-terminal region (residues 1-29) might play a role in centriole retention.
  • Cellular localization

    Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole. Cytoplasm, cytoskeleton, cilium basal body. Cytoplasm, cytoskeleton, cilium axoneme. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, flagellum axoneme. In multi-ciliated cells, localizes to the basal bodies and in non-ciliated cells, to the centrosome. In spermatozoa, colocalizes with microtubules along the length of the axoneme from its proximal end to its distal tip and with tubulin at the distal end of the flagellum and at the proximal centriole.
