Predicted to be an extracellular matrix structural constituent. Predicted to be involved in extracellular matrix organization and hemidesmosome assembly. Predicted to be integral component of membrane. Predicted to be part of collagen trimer. Predicted to be active in extracellular matrix; extracellular space; and hemidesmosome. 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]
