| Tissue Specificity | Expressed primarily in the granular layer of the epidermis and inner root sheath of hair follicles. In psoriatic skin, expressed throughout the stratum corneum. In ulcerated skin, expressed in the stratum granulosum of intact epidermis but almost absent from ulcerated regions. Expressed in differentiated areas of squamous cell carcinomas but not in undifferentiated tumors. |
| Post Translational Modifications | Undergoes autocleavage which is necessary for activation of the protein. |
| Function | Protease responsible for filaggrin processing, essential for the maintenance of a proper epidermis organization. |
