Definition / general
  • Molecular weight of 56.5 kDa
  • Partner of CK1
  • CK1 and CK10 are present in suprabasal terminally differentiating cells
  • Mutations in CK10 or CK1 cause epidermolytic hyperkeratosis / bullous congenital ichthyosiform erythroderma of Brocq (Hum Mol Genet 2006;15:1133, Dermatol Online J 2006;12:6); defects of CK10-CK1 protein network cause structural instability and weakness of keratinocytes, causing blistering, hyperproliferation and hyperkeratosis
  • CK10 is putative autoantigen in chronic, antibiotic resistant Lyme arthritis (J Immunol 2006;177:2486)
