    text
  • pericentriolar localization, in the basal body in primary cilia
  • localizes both to the primary cilium and to the nucleus
  • not exclusively localized to the centrosome and basal body, but is present also in the nucleus
    • basic FUNCTION
  • may play a role in differentiation of metanephric precursor cell
  • may have a role beyond primary cilium organization and assembly and in left-right axis specification
  • playing roles not only in microtubule organization (centrosomal function) but also in mechanosensation of urine flow (a primary ciliary function)
  • able to self-associate and this interaction is mediated by its coiled-coil rich region
  • may be part of a multi-protein complex and could play different biological functions in the centrosome-primary cilium organelles as well as in the nuclear compartment
  • necessary for correct ciliogenesis in the limb bud but not for cilia outgrowth, in contrast to what was previously shown for the embryonic node
  • plays a role in regulating digit number and identity during limb and skeletal patterning increasing insight on the functional role of primary cilia during development
  • plays a crucial role in forebrain development, and in particular, in the control of dorso-ventral patterning and early corticogenesis
  • functions after docking and before elaboration of the axoneme
  • at centriolar satellites functions as a crucial suppressor of primary ciliogenesis in human cancer cells
  • at centriolar satellites has a crucial role in suppressing primary ciliogenesis, whereas OFD1 at centrioles has been shown to be essential for primary ciliogenesis
  • BBS4 and OFD1 interacted with proteasomal subunits, and loss of either BBS4 or OFD1 led to depletion of multiple subunits from the centrosomal proteasome
  • OFD1 and FOPNL are known to regulate the integrity of the centriole distal end, confirming that this structural element is a target of importance for pathogenic mutations in ciliopathies

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • directly binds to the ciliary protein lebercilin, encoded by LCA5
  • interacting with RUVBL1
  • direct interaction of FAM161A with lebercilin (LCA5), CEP290, OFD1 and SDCCAG8, all involved in hereditary retinal degeneration
  • localizes to centriolar satellites, interacting with proteins associated with human ciliary disease, PCM1, CEP290 and BBS4
  • C2CD3 physically associates with OFD1
  • KIAA0753vdirectly interacts with OFD1 in the absence of FOPNL, but the interaction between KIAA0753 and OFD1 is much stronger when FOPNL is present in the complex
  • SDCCAG8 interacts with proteins of the centriolar satellites (OFD1, AZI1), of the endosomal sorting complex (RABEP2, ERC1), and with non-muscle myosin motor proteins (MYH9, MYH10, MYH14) at the centrosome

    ANIMAL & CELL MODELS
  • animal model which could represent a valuable tool to shed light on the molecular link between mTOR and cysts development and eventually to the identification of novel drug targets for renal cystic disease
  • in autophagy-deficient Atg5 or Atg3 null mouse embryonic fibroblasts, Ofd1 accumulates at centriolar satellites, leading to fewer and shorter primary cilia and a defective recruitment of Bbs4 (Bardet–Biedl syndrome 4) to cilia
