MAGEB3 Gene

Name melanoma antigen family B3
Description This gene is a MAGE-B subfamily member of the MAGE gene family. MAGE family member proteins direct the expression of tumor antigens recognized on a human melanoma by autologous cytolytic T lymphocytes. There are two known clusters of MAGE genes on chromosome X. The members of the MAGE-A subfamily are located in the Xq28 region, while the members of the MAGE-B subfamily are clustered in the Xp21 region. [provided by RefSeq, Jul 2008]
Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\n MAGEB3, a member of the melanoma‐associated antigen (MAGE) family, performs multifaceted roles in both epigenetic regulation and tumor biology. On one hand, MAGEB3 has been implicated in the process of X chromosome inactivation. Specifically, it interacts with Polycomb group proteins (via Pcgf3), thereby contributing to the recruitment of the Polycomb complex and promoting H3K27 tri‐methylation along the inactive X chromosome, a key event for stable gene silencing."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n \n "}, {"type": "p", "children": [{"type": "t", "text": "\n On the other hand, as a cancer–testis antigen it is normally silent in most adult tissues (except testis) but becomes aberrantly expressed in various tumors.
