Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 121 kDa.
  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Function

      Serine protease inhibitor, probably important for the anti-inflammatory and/or antimicrobial protection of mucous epithelia. Contribute to the integrity and protective barrier function of the skin by regulating the activity of defense-activating and desquamation-involved proteases. Inhibits KLK5, it's major target, in a pH-dependent manner. Inhibits KLK7, KLK14 CASP14, and trypsin.
    • Tissue specificity

      Highly expressed in the thymus and stratum corneum. Also found in the oral mucosa, parathyroid gland, Bartholin's glands, tonsils, and vaginal epithelium. Very low levels are detected in lung, kidney, and prostate.
    • Involvement in disease

      Defects in SPINK5 are the cause of Netherton syndrome (NETH) [MIM:256500]. NETH is an autosomal recessive congenital ichthyosis associated with hair shaft abnormalities and anomalies of the immune system. Typical features are ichthyosis linearis circumflexa, ichthyosiform erythroderma, trichorrhexis invaginata (bamboo hair), atopic dermatitis, and hayfever. High postnatal mortality is due to failure to thrive, infections and hypernatremic dehydration.
    • Sequence similarities

      Contains 15 Kazal-like domains.
    • Domain

      Contains at least one active inhibitory domain for trypsin (domain 6).
    • Post-translational

      Proteolytically processed by furin in individual domains (D1, D5, D6, D8 through D11, and D9 through D15) exhibiting various inhibitory potentials for multiple proteases.
