desmocollin 3

Also known as: CDHF3, DSC, DSC1, DSC2, DSC4, HT-CP

Desmocollin-3 is a calcium-dependent glycoprotein that forms part of desmosome cell-cell junctions, functioning as an adhesive protein essential for epidermal cell adhesion, dermal barrier function, and hair shaft anchorage. Mutations cause hypotrichosis and recurrent skin vesicles, a disorder affecting hair growth and skin integrity. This condition follows autosomal recessive inheritance.
