  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      May function as a regulator of both motility- and head-associated functions such as capacitation and the acrosome reaction.
    • Tissue specificity

      Testis specific; only expressed in spermatids.
    • Sequence similarities

      Belongs to the AKAP110 family.
    • Domain

      RII-binding site, predicted to form an amphipathic helix, could participate in protein-protein interactions with a complementary surface on the R-subunit dimer.
    • Post-translational

      Phosphorylated on tyrosine residues.
    • Cellular localization

      Cytoplasmic vesicle > secretory vesicle > acrosome. Ribs of the fibrous sheath in the principal piece of the sperm tail. Dorsal margin of the acrosomal segment.
