Predicted to be an extracellular matrix structural constituent. Predicted to be involved in extracellular matrix organization and hemidesmosome assembly. Located in hemidesmosome. Is expressed in several structures, including esophagus; genitourinary system; oral epithelium; sensory organ; and skin. Used to study bullous pemphigoid and junctional epidermolysis bullosa non-Herlitz type. Human ortholog(s) of this gene implicated in epithelial recurrent erosion dystrophy; junctional epidermolysis bullosa; and junctional epidermolysis bullosa non-Herlitz type. Orthologous to human COL17A1 (collagen type XVII alpha 1 chain). [provided by Alliance of Genome Resources, Apr 2022]
