Desmocollin-1, also known as Cadherin family member 1 (CDHF1), is encoded by the DSC1 gene in human. Desmocollin-1 is a calcium-dependent glycoprotein that is a member of the desmocollin subfamily of the cadherin superfamily. Desmocollins, along with the desmogleins, are found primarily in epithelial cells where they constitute the desmosomes, a type of cell junction required for cell adhesion. Desmocollins contain an amino-terminal extracellular domain or ectodomain or EC domain that is followed by a transmembrane domain and a carboxyl-terminal intracellular domain. The extracellular domain mediates intercellular interactions in the desmosome whereas the intracellular domain mediates Desmocollin interaction with intermediate filaments. The DSC1 gene comprises 17 exons spanning approximately 33 kb on 18q12.1, and the DSC3 gene comprises 17 exons spanning approximately 49 kb on 18q12.1. Alternative splicing gives rise to two DSC1 and DSC3 isoforms, designated 1A and 1B, and 3A and 3B, r

EGFR [31G7]

Epidermal growth factor receptor (EGFR) is a 170 kDa transmembrane glycoprotein receptor tyrosine kinase that, activated by epidermal growth factor (EGF), affects cell growth and differentiation. Binding of EGF or TGF alpha to EGFR activates tyrosine kinase activity of the receptor. Phosphorylation of Tyr 992, Tyr 1068 and Tyr 1086 is required for conformational change in the C-terminal of EGFR. Autophosphorylation of Tyr 992 creates a binding site for the phospholipase C-gamma (PLC-gamma) SH2 domain, inducing downstream signaling. In breast cancer, EGFR is predorminately expressed in basal cell-like carcinoma, it has been recommendated for identification of basal-like breast carcinoma along with Cytokeratin 5/6.
