- CITATIONS: 1
|Calculated MW||51561 Da|
|Other Names||Keratin, type I cytoskeletal 14, Cytokeratin-14, CK-14, Keratin-14, K14, KRT14|
|Target/Specificity||A synthetic peptide corresponding to residues near the C-terminus of human Cytokeratin 14 was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Cytokeratin-14 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||The nonhelical tail domain is involved in promoting KRT5-KRT14 filaments to self-organize into large bundles and enhances the mechanical properties involved in resilience of keratin intermediate filaments in vitro.|
|Cellular Location||Cytoplasm. Nucleus. Note=Expressed in both as a filamentous pattern|
|Tissue Location||Detected in the basal layer, lowered within the more apically located layers specifically in the stratum spinosum, stratum granulosum but is not detected in stratum corneum. Strongly expressed in the outer root sheath of anagen follicles but not in the germinative matrix, inner root sheath or hair. Found in keratinocytes surrounding the club hair during telogen.|

Keratins are cytoplasmic intermediate filament proteins expressed by epithelial cells. Cytokeratin 14 (CK-14) is a 50-kDa keratin expressed in abundance in human epidermal cells (1). During anagen, cell proliferation in the germinative matrix of the hair follicle gives rise to the fiber and inner root sheath. The transition from anagen to telogen is marked by downregulation of hair cortical specific keratins and the appearance of CK-14 in the epithelial sac to which the telogen hair fiber is anchored (2). A family with recessive epidermolysis bullosa simplex lacked expression of the basal cell keratin 14. The patients had severe generalized skin blistering that improved slightly with age. The basal cells of the patients did not express keratin 14 and contained no keratin intermediate filaments. The expression of keratin 5, the obligate copolymer of keratin 14, was slightly reduced (3).
