    basic FUNCTION
  • important for appropriate photoreceptor formation during development and/or survival following differentiation
  • playing an essential role in processing of farnesylated proteins in retina
  • enhances the stability of cGMP phosphodiesterase and is essential for photoreceptor viability
  • a specialized chaperone required for rod phosphodiesterase biosynthesis
  • required for the normal accumulation of cone phosphodiesterase
  • plays a direct role in cones and is needed for a proper light response from cone photoreceptor cells
  • needed for the proper functioning and survival of cone photoreceptors
  • may have a role in directly regulating the UBD conjugation machinery
  • CELLULAR PROCESS protein, post translation, folding

    protein
  • NEDD8 Ultimate Buster 1, NUB1
  • farnesylated proteins
  • interacting with HSP90 and HSP70 (specialized role of AIPL1 in photoreceptors may be modulated by the molecular chaperones Hsp90 and Hsp70, and this association may be important in the pathogenesis of LCA)
  • interacting with PDE6A and is needed for the proper assembly of functional rod PDE6 subunits
  • AIPL1 interact with NUB1, which facilitates the proteasomal degradation of proteins modified with the ubiquitin-like protein UBD
  • NEUROD1 may act through AIPL1 and other genes to maintain photoreceptor homeostasis
  • cell & other

    . strong and stable rescue retinal degeneration in Aipl1 null and Aipl1 hypomorphic (Aipl1hypo) mutant mice using AAV8 vector containing the human RK promoter, which is only active in both types of photoreceptors
    ANIMAL & CELL MODELS
  • Aipl1-/- mice have highly disorganized, short, fragmented photoreceptor outer segments and lack both rod and cone electroretinogram responses
  • knockdown of AIPL1 expression in mice produces a retinopathy with a reduction in the level of rod cGMP phosphodiesterase expression
  • Aipl1-/- mouse displays rapid retinal degeneration and massive Müler cell gliosis
  • mouse with rods expressing lowered amounts of AIPL1 delayed the photoresponse, decreased its amplification constant, slowed a rate-limiting step in its recovery, and limited the light-induced decrease in Ca2
  • in mice lacking endogenous Aipl1, rod-specific expression of hAIPL1 protein completely rescues rod outer segment ultrastructure
  • restoration of cellular function and preservation of photoreceptor cells and retinal function in Aipl1 h/h mice following gene replacement therapy using an AAV2/2 vector and in the light accelerated Aipl1 h/h model and Aipl1-/- mice using an AAV2/8 vector
