title: MAGE-11 protein is highly conserved in higher organisms and located predominantly in the nucleus.
abstract: The MAGE-11 gene belongs to a family whose products were identified first in tumor tissue. The MAGE-11 gene product has not been characterized in detail. We have isolated MAGE-11 cDNA from HeLa cells and confirmed the presence of MAGE-11 protein and of at least 2 other MAGE proteins (MAGE-1 and MAGE-3) in this cell line. Monoclonal antibodies (MAbs), obtained by using a GST-MAGE-11 fusion protein, detect MAGE-11 protein in HeLa cells as a 48 kDa protein. In contrast to other known proteins of the MAGE family, MAGE-11 is found mainly in the nucleus. Immunoprecipitation out of whole-cell extracts from different species reveals that MAGE-11 protein is highly conserved among mammalian cells, suggesting a conserved and important function.
