EpCAM (epithelial cell adhesion molecule, also known as Trop-1) and Trop-2 (also known as tumor-associated calcium signal transducer 2, TACSTD2) are transmembrane glycoproteins that belong to the tumour-associated calcium signal transducer (TACSTD) family. They are evolutionarily related and both are implicated in signaling triggered by proteolytic cleavage within the ectodomain [1,3]. They share an overall similar structure but differ in their dimers formation. They consist of an ectodomain with an N-terminal, thyroglobulin type-1 (TY, Pfam:PF00086) and C-terminal domains. This entry represents the C-terminal domain of EpCAM and Trop-2, which has an alpha+beta fold [1-3].	Domain

Structure analysi ...	EpCAM (epithelial cell adhesion molecule), a stem and carcinoma cell marker, is a cell surface protein involved in homotypic cell-cell adhesion via intercellular oligomerization and proliferative signalling via proteolytic cleavage. Structure analysis indicate that it is composed of three domains: N-domain, Thyroglobulin type-1A (TY) domain and the C-terminal domain. This entry represents the small and compact disulphide-rich N-terminal domain of 39 amino-acid residues [1]. Trop-2 (also known as tumor-associated calcium signal transducer 2, TACSTD2) is also included in this entry, as they are evolutionarily related and both are implicated in signaling triggered by proteolytic cleavage within the ectodomain [1-3]. They share an overall similar structure but differ in their dimers formation.	Domain
