motifs/domains
  • a calponin-homology domain within the IFT81 N-terminus and the highly basic N-terminus of IFT74 form a module for IFT of tubulin (
  • a putative signal peptide
  • four coiled-coil domains
    • HOMOLOGY
    interspecies homolog to murine Ift81 (92.9pc)
    homolog to rattus Cdv1 (92.7pc)

    text expression level is increased with testis development
    basic FUNCTION
  • may play an important role in sperm maturation
  • tubulin binding by IFT81 was required for ciliogenesis
  • two core IFT proteins IFT74 and IFT81 form a tubulin-binding module
  • together, the IFT81 and IFT74 N-termini are crucial for flagellar assembly, and are likely to function as the main module for IFT of tubulin
  • importance of IFT81 in the skeleton, and role in the anterograde transport complex
  • involved in the bidirectional transport of ciliary proteins

    small molecule
    protein
  • IFT81 and IFT74/72 directly interact to form a higher order oligomer consistent with a tetrameric complex
  • IFT52 binds directly to four other IFT-B subunits, IFT81/74/27/HSPB11
