Keratin 1 (KRT1), also called cytokeratin 1 (CK1) or K1, is a type II intermediate filament protein. It forms heterodimers with KRT10 to build the intermediate filament network in upper epidermal layers, sustaining cellular structural integrity and skin barrier function. It regulates epidermal terminal differentiation, participating in cell polarity maintenance and balancing proliferation-differentiation signals.
Mutations in KRT1 cause congenital bullous ichthyosiform erythroderma and epidermolysis bullosa simplex, marked by blistering and scaling. Current treatments include topical retinoids for keratinization modulation. Preclinical studies explore targeted approaches like gene editing or protein replacement to correct KRT1 defects, aiming to restore skin barrier homeostasis.
KRIT1 Antibody (CSB-PA012501LA01HU)
Validated Data
IHC image of CSB-PA012501LA01HU diluted at 1:600 and staining in paraffin-embedded human colon cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of HepG2 cells with CSB-PA012501LA01HU at 1:200, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
