    basic FUNCTION
  • role in the regulation of activation of the mammalian stress response via the c-Jun N-terminal kinase (JNK)-signaling pathway
  • may act as a scaffold protein that may assemble active IKK-MAP3K14 complexes (IKKA, IKKB and MAP3K14/NIK)
  • may play a role in oligodendrocyte differentiation and/or myelin formation
  • role in cell adhesion and migration
  • crucial for both vascular and neural development during embryogenesis and that protein function is conserved between mouse and human
  • involved in cytoskeleton regulation
  • involved in cell adhesion and migration through cytosolic interactions
  • involved in regulating the expression of the microtubules (MT) destabilizing protein STMN2, and STMN2 elevation observed in IKBKAP-deficient cells can alter the MT organization and dynamics which could play a pivotal role in familial dysautonomia
  • plays pleiotropic roles in both the peripheral and central nervous systems
  • novel function of ELP1 in meiosis, suggesting that ELP1 contributes to this process partly by exerting its effect on transcription and tRNA modification
  • ELP1, ELP2, ELP3, ELP4, ELP5, ELP6 plays vital roles in gene regulation
  • encoding the scaffolding protein for the Elongator complex

    a component
  • component of the IKK (Ikappa B kinase)complex
  • core Elongator complex formed by IKBKAP, ELP2, and ELP3 was rather stable, whereas ELP4, ELP5, and ELP6 might loosely contact and work together with the core Elongator to regulate cell functions

    Therapy target
  • treatment of Familial dysautonomia lymphoblast cell lines with kinetin increases IKBKAP mRNA and IKAP protein to normal levels
  • kinetin is capable to alter the IKBKAP splicing in the transgenic mice carrying the Familial dysautonomia BAC containing the the IVS20+6T>C splice site mutation and to correct the IKBKAP splicing in all major tissues including the brain

    kinetin therapeutic in dysautonomia and perhaps in other splicing disorder
    ANIMAL & CELL MODELS
  • various RNA-interference-based depletions of IKAP lead to defective adhesion and migration in several cell types, including rat primary neurons
  • in the mouse model carrying the complete human IKBKAP locus with the FD IVS20+6T-->C splice mutation, the mutant IKBKAP transgene is misspliced in this model in a tissue-specific manner that replicates the pattern seen in familial dysautonomia patient tissues
  • Depletion of IKAP resulted in a significant decrease in filamin A localization in membrane ruffles and defective actin cytoskeleton organization
  • mouse lines caring the human IVS20+6T>C splice site mutation in the IKBKAP gene exhibit the same tissue-specific aberrant splicing patterns as seen in Familial dysautonomia patients
