  • Involvement in disease

    Defects in KRT5 are a cause of epidermolysis bullosa simplex Dowling-Meara type (DM-EBS) [MIM:131760]. DM-EBS is a severe form of intraepidermal epidermolysis bullosa characterized by generalized herpetiform blistering, milia formation, dystrophic nails, and mucous membrane involvement.
    Defects in KRT5 are the cause of epidermolysis bullosa simplex with migratory circinate erythema (EBSMCE) [MIM:609352]. EBSMCE is a form of intraepidermal epidermolysis bullosa characterized by unusual migratory circinate erythema. Skin lesions appear from birth primarily on the hands, feet, and legs but spare nails, ocular epithelia and mucosae. Lesions heal with brown pigmentation but no scarring. Electron microscopy findings are distinct from those seen in the DM-EBS, with no evidence of tonofilament clumping.
    Defects in KRT5 are a cause of epidermolysis bullosa simplex Weber-Cockayne type (WC-EBS) [MIM:131800]. WC-EBS is a form of intraepidermal epidermolysis bullosa characterized by blistering limited to palmar and plantar areas of the skin.
    Defects in KRT5 are a cause of epidermolysis bullosa simplex Koebner type (K-EBS) [MIM:131900]. K-EBS is a form of intraepidermal epidermolysis bullosa characterized by generalized skin blistering. The phenotype is not fundamentally distinct from the Dowling-Meara type, althought it is less severe.
    Defects in KRT5 are the cause of epidermolysis bullosa simplex with mottled pigmentation (MP-EBS) [MIM:131960]. MP-EBS is a form of intraepidermal epidermolysis bullosa characterized by blistering at acral sites and 'mottled' pigmentation of the trunk and proximal extremities with hyper- and hypopigmentation macules.
    Defects in KRT5 are the cause of Dowling-Degos disease (DDD) [MIM:179850]; also known as Dowling-Degos-Kitamura disease or reticulate acropigmentation of Kitamura. DDD is an autosomal dominant genodermatosis. Affected individuals develop a postpubertal reticulate hyperpigmentation that is progressive and disfiguring, and small hyperkeratotic dark brown papules that affect mainly the flexures and great skin folds. Patients usually show no abnormalities of the hair or nails.

  • Cervix consists of two distinct KRT5+ stratified and KRT7+/8+ columnar epithelial lineages.

    Panel D shown only.

    Transition zone (TZ) including stratified and columnar epithelium from human (A,C) and mouse (B, D) cervix tissue sections immunolabeled with antibodies against KRT5 (ab193894) and KRT8; nuclei are shown in blue.

    Organoids were washed five times with cold PBS to remove Matrigel before fixing with 4% paraformaldehyde for 1 h at room temperature (RT) followed by washing with PBS twice. Organoids were then subjected to dehydration in an ascending ethanol series followed by isopropanol and acetone for 20 min each. The dehydrated organoids were paraffin-embedded and 5 µM sections cut on a Microm HM 315 microtome. Mouse and human tissues were extensively washed with PBS and fixed using 4% PFA overnight at RT. Samples were subjected to dehydration in an ascending ethanol series followed by isopropanol and xylene (60 min each) followed by paraffinization using a Leica TP1020 tissue processor. The tissue was embedded and 5 µM sections cut on a microtome. For immunostaining, paraffin sections were deparaffinized and rehydrated, followed by treatment with antigen retrieval solution. Sections were blocked using blocking buffer (1% BSA and 2% FCS in PBS) for 1 h at RT. Primary antibodies were diluted in blocking buffer and incubated for 90 mins at RT followed by five PSB washes before 1 h incubation with secondary antibodies diluted in blocking buffer along with Hoechst or Draq5. Sections were washed with PBS five times and mounted. Images were acquired with a Leica TCS SP8 confocal microscope.

  • Flow Cytometry analysis of A431 (human epidermoid carcinoma) cells labeling Cytokeratin 5 with purified ab193894 at 1/500 dilution(10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(/) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) was used as the unlabeled control.

  • ab193894 staining Cytokeratin 5 in HACAT cells. The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 10% normal goat serum in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab193894 at 1/200 dilution (shown in green) and ab195889, Mouse monoclonal to alpha Tubulin (Alexa Fluor® 594), at 1/200 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).
    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
