Function Plays a significant role in maintaining keratin filament organization in intestinal epithelia. When phosphorylated, plays a role in the secretion of mucin in the small intestine.
Tissue Specificity
Expressed predominantly in the intestinal epithelium. Expressed in luminal cells of colonic mucosa. Also expressed in the Merkel cells of keratinized oral mucosa; specifically at the tips of some rete ridges of the gingival mucosa, in the basal layer of the palatal mucosa and in the taste buds of lingual mucosa.

Estrogen sig.ling pathway (hsa04915 )
Staphylococcus aureus infection (hsa05150 )
Reactome Pathway
Formation of the cornified envelope (R-HSA-6809371 )
Keratinization (R-HSA-6805567 )
