Activity summary

Mammaglobin A also known as MGB1 is a breast-specific protein of approximately 93 amino acids with a molecular mass of about 15 kDa. It has a high expression in mammary tissue and limited expression in other tissues like the sweat glands. Researchers use immunohistochemistry (IHC) to detect Mammaglobin in tissue samples because of its tissue-specific expression making it a useful marker for breast epithelium.

Biological function summary

Mammaglobin A functions as a glycoprotein. Its precise biological role remains unclear but scientists propose it plays a role in secretory processes due to its presence in epithelial cells of the mammary glands. This protein itself is not known to participate in a larger complex. The significance of Mammaglobin A as a marker rather than an active enzyme or receptor suggests its potential involvement in processes specific to breast tissue.

Pathways

Mammaglobin A interacts within pathways involving sex steroid hormone signaling reflecting its expression in mammary tissue. This protein's expression is possibly regulated by hormonal pathways like the estrogen pathway which plays a significant role in breast tissue development and differentiation. It does not actively participate with related proteins but might be an indicator of pathway activities associated with specific tissues or conditions.

Associated diseases and disorders

Mammaglobin A is prominently associated with breast cancer. Its specific expression in breast tissue makes it a valuable marker for detecting disseminated breast tumor cells. Although it does not directly interact with proteins involved in cancer progression like HER2 or ER (estrogen receptor) its expression levels serve as an important biomarker for diagnosis and monitoring treatment response. Researchers continue to explore its potential utility in understanding breast cancer biology and improving clinical outcomes.
