| Tissue Specificity | Expressed in the stratum spinosum of the epidermis. Weak expression is detected in the stratum granulosum. |
| Function | Thiol protease which is believed to participate in intracellular degradation and turnover of proteins. Cleaves matrix extracellular phosphoglycoprotein MEPE. Involved in the solubilization of cross-linked TG/thyroglobulin in the thyroid follicle lumen. Has also been implicated in tumor invasion and metastasis. |
