Epstein–Barr virus latent membrane protein 1 (LMP1) is an Epstein–Barr virus (EBV) protein that regulates its own expression and the expression of human genes. LMP1 has a molecular weight of approximately 63 kDa, and its expression induces many of the changes associated with EBV infections and activation of primary B cells. LMP1 is the best-documented oncoprotein of the EBV latent gene products, as it is expressed in most EBV-related human cancers. The structure of LMP1 consists of a short cytoplasmic N-terminus tail, six trans-membrane domains, and a long cytoplasmic C-terminus, which contains three activating domains: CTARt, CTAR2, and CTAR3. Each CTAR domain contains an amino acid sequence that serves as a recognition site for cellular adaptors to bind and trigger a series of signal transduction pathways that can lead to a change in gene expression. LMP-1 mediates signaling through the tumor necrosis factor-alpha/CD40 pathway. It is often found in Reed–Sternberg cells. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Epstein–Barr virus latent membrane protein 1」の詳細全文を読む スポンサード リンク
