  • Function

    Component of the cornified envelope of keratinocytes. May be involved in the interplay between adherens junctions and desmosomes. The function in the nucleus is not known.
  • Tissue specificity

    Isoform 2, isoform 3 and isoform 4 are expressed in several cell lines including keratinocytes and bladder and epidermoid carcinoma (at protein level). Isoform 2, isoform 3 and isoform 4 are expressed in hair follicle and interfollicular epidermis (at protein level).
  • Sequence similarities

    Belongs to the kazrin family.
    Contains 3 SAM (sterile alpha motif) domains.
  • Cellular localization

    Cytoplasm > cytoskeleton and Cytoplasm. Cell junction > desmosome. Nucleus. Observed at the apical plasma mebrane of keratinocytes. Partially colocalizes with PPL and DP at desmosomes, and with PP at the interdesmosomal plasma membrane. Colocalizes with cortical actin-based membrane structures.

    Several isoforms of Kazrin are expressed in human keratinoctyes. KazrinE is the longest isoform and has a predicted molecular weight of 86 kDa, however is expected to show a banding pattern around 100 kDa within western blotting. KazrinA is the most abundant isoform and has a predicted molecular weight of 47 kDa, however shows a banding pattern around 53 kDa on a western blot. Abcam recommends using milk (2%) as the blocking agent. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
  • ICC/IF image of ab74114 stained SKNSH cells. The cells were 4% PFA 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 (ab74114, 5µg/ml) 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.
