Activity summary

Cytokeratin 15 often abbreviated as CK15 bsa-15 or keratin 15 is an intermediate filament protein known for its role in the structural integrity of epithelial cells. It weighs approximately 50 kilodaltons. This protein is mainly expressed in the basal layer of stratified squamous epithelia such as the epidermis and the hair follicle. CK15 is an essential part of the cytoskeleton contributing to cell shape and mechanical resilience.

Biological function summary

CK15 plays a significant role in maintaining epithelial stem cell populations. It is part of the keratin protein family where it forms a complex network with other cytokeratins to support epithelial cell stability. CK15 has been shown to mark epithelial progenitor cells hinting at its role in tissue regeneration and repair. Its expression levels often reflect the cellular origin and differentiation state particularly in the skin and associated structures.

Pathways

CK15 is involved in pathways related to epithelial cell differentiation and homeostasis. It interacts within the cytoskeletal network alongside other cytokeratins like keratin 5. CK15 contributes to pathways that regulate cell proliferation and differentiation. It participates in the wound healing process where keratin 6 and keratin 17 also play important roles. This involvement allows it to impact how epithelial cells respond to and repair after damage.

Associated diseases and disorders

CK15 has been associated with skin disorders and certain types of cancers. Its expression is often altered in squamous cell carcinoma and basal cell carcinoma where abnormal CK15 levels can influence tumor behavior. Additionally changes in CK15 expression are linked to alopecia relating it to proteins like keratin 5 and keratin 8 which have similar expression patterns in hair follicles. Understanding CK15's role may aid in developing biomarkers for diagnosis and therapeutic targets.
