Biotin-Desmoglein-3 DSG3 (50-79) - Biotin Labeled

Desmoglein-3 DSG3 (50-79) is derived from the pemphigus vulgaris antigen DSG3 and is involved in cell-cell adhesion. It can exist as non-junctional and junctional and is one of the desmosomal cadherins. Within the epithelial cells non-junctional DSG3 takes part in E-cadherin signalling. The overexpression of DSG3 has been observed in squamous cell carcinoma and can be used as a biomarker for cervical sentinel lymph nodes. DSG3 in tumours is considered as being pro-metastatic through DSG3 ability to activate AP-1 and the PKC/Ezrin pathway. Biotin (B7) has been added to the N-terminus.
