Anti-Cytokeratin 1/KRT1 Antibody Picoband® Fluoro488 Conjugated

Keratin 1 is a Type II intermediate filament (IFs) of the intracytoplasmatic cytoskeleton. The protein encoded by this gene is a member of the keratin gene family. The type II cytokeratins consist of basic or neutral proteins which are arranged in pairs of heterotypic keratin chains coexpressed during differentiation of simple and stratified epithelial tissues. This type II cytokeratin is specifically expressed in the spinous and granular layers of the epidermis with family member KRT10 and mutations in these genes have been associated with bullous congenital ichthyosiform erythroderma. The type II cytokeratins are clustered in a region of chromosome 12q12-q13.

Controls cell proliferation in a tissue-specific manner and is involved in morphogenesis. During embryonic development, exerts a role in the expansion of muscle progenitors. May play a role in the proper localization of asymmetric organs such as the heart and stomach. IsoformPTX2Cis involved in left-right asymmetry the developing embryo (By similarity) .
