  • Tissue specificity

    Expressed in prostate.
  • Involvement in disease

    Defects in KLK4 are the cause of amelogenesis imperfecta hypomaturation type 2A1 (AI2A1) [MIM:204700]. AI2A1 is an autosomal recessive defect of enamel formation. The disorder involves both primary and secondary dentitions. The teeth have a shiny agar jelly appearance and the enamel is softer than normal. Brown pigment is present in middle layers of enamel.
  • Sequence similarities

    Belongs to the peptidase S1 family. Kallikrein subfamily.
    Contains 1 peptidase S1 domain.
