Tissue SpecificityExpressed in the basal skin layer (at protein level) (PubMed:30009832). Squamous epithelia cell-specific. Expressed in the esophagus (periphery of the cells of the granular and the upper spinous layers), foreskin (granular and lower cornified cells), scalp skin (granular layer), inner root sheath of the hair follicle and in primary keratinocytes (at protein level). Expressed in the squamous epithelium of the cervix, esophagus, foreskin and larynx. Expressed in the fetal bladder and scalp skin. Expressed at very low levels in the lung, kidney, uterus, skeletal muscle, heart and fetal brain. Undetectable or barely detectable in esophageal and oral squamous cell carcinoma compared with the matched adjacent normal esophageal mucosa. Undetectable or barely detectable in larynx and esophagus from patients with pH-documented laryngopharyngeal reflux (LPR). {ECO:0000269|PubMed:11056050, ECO:0000269|PubMed:11606197, ECO:0000269|PubMed:15854041, ECO:0000269|PubMed:15896671, ECO:0000269|PubMed:16466100, ECO:0000269|PubMed:16640557, ECO:0000269|PubMed:17289885, ECO:0000269|PubMed:30009832}.
