Tissueskin, lower.leg.skin
Tissue SpecificityExpressed in the upper spinous and granular suprabasal layers of normal adult epidermal tissues from most body sites including thigh, breast nipple, foot sole, penile shaft and axilla. Not present in foreskin, squamous metaplasias and carcinomas. Expression in hypertrophic and keloid scars begins in the deepest suprabasal layer. Weakly expressed in normal gingiva and tongue, however expression is induced in benign keratoses of lingual mucosa and in mild-to-moderate oral dysplasia with orthokeratinization. {ECO:0000269|PubMed:10233306, ECO:0000269|PubMed:12598329, ECO:0000269|PubMed:1380918}.
