  • FunctionAggregates keratin intermediate filaments and promotes disulfide-bond formation among the intermediate filaments during terminal differentiation of mammalian epidermis.
  • Tissue specificityKeratohyalin granules.
  • Involvement in diseaseIchthyosis vulgaris
    Dermatitis atopic 2
  • Sequence similaritiesBelongs to the S100-fused protein family.
    Contains 2 EF-hand domains.
    Contains 23 filaggrin repeats.
  • Post-translational
    Filaggrin is initially synthesized as a large, insoluble, highly phosphorylated precursor containing many tandem copies of 324 AA, which are not separated by large linker sequences. During terminal differentiation it is dephosphorylated and proteolytically cleaved. The N-terminal of the mature protein is heterogeneous, and is blocked by the formation of pyroglutamate.
    Undergoes deimination of some arginine residues (citrullination).

Anti-Filaggrin antibody images

  • ICC/IF image of ab81468 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab81468, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h.Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
