Trop-2 plays a role in tumor progression by actively interacting with several key molecular signaling pathways traditionally associated with cancer development and progression. Aberrant overexpression of Trop-2 has been described in several solid cancers, such as colorectal, renal, lung, and breast cancers.

Tumor-associated calcium signal transducer 2, also known as Trop-2 and as epithelial glycoprotein-1 antigen (EGP-1)[5] is a protein that in humans is encoded by the TACSTD2 gene.[6][7][8]

This intronless gene is located at the short arm of chromosome 1 (1p32.1).[9] It encodes a carcinoma-associated antigen defined by the monoclonal antibody GA733. This antigen is a member of a family including at least two type I membrane proteins. It transduces an intracellular calcium signal and acts as a cell surface receptor.

Mutations of this gene result in gelatinous drop-like corneal dystrophy, an autosomal recessive disorder characterized by severe corneal amyloidosis leading to blindness.[8]

Trop-2 expression was originally described in trophoblasts (placenta) and fetal tissues (e.g., lung). Later, its expression was also described in the normal stratified squamous epithelium of the skin, uterine cervix, esophagus, and tonsillar crypts.[10]

Trop-2 plays a role in tumor progression by actively interacting with several key molecular signaling pathways traditionally associated with cancer development and progression. Aberrant overexpression of Trop-2 has been described in several solid cancers, such as colorectal, renal, lung, and breast cancers. Trop-2 expression has also been described in some rare and aggressive malignancies, e.g., salivary duct, anaplastic thyroid, uterine/ovarian, and neuroendocrine prostate cancers.[10] This overexpression is caused by deregulations at a transcriptional and posttranscriptional level.[9]

Trop-2 causes cancer cell growth, proliferation, invasion, migration, and survival of cancer cells, which leads to Trop-2 being associated with tumor aggressiveness and poor prognosis. This is also confirmed by the fact, that the proliferation of tumor cells is disturbed when Trop-2 is knocked down. These facts make Trop-2 a possible prognostic biomarker to identify high-risk patients, as well as an attractive therapeutic target for late-stage diseases[9]

This antigen is the target of sacituzumab govitecan and datopotamab deruxtecan (Dato-DXd),[11] both antibody-drug conjugates.
