    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
  • plays an essential role during spermatogenesis by modulating the assembly and elongation of the sperm flagella

    a component
  • core component of the IFT-B complex
  • INTERACTION
    DNA
    RNA
    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
  • IFT74 and IFT81 interact directly through central and C-terminal coiled-coil domains, and the N termini of these proteins form a tubulin-binding module important for ciliogenesis
  • 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
