SON protein is a protein that in humans is encoded by the ''SON'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=6651 )〕 SON is the name that has been given to a large Ser/Arg (SR)-related protein, which is a splicing co-factor that contributes to an efficient splicing within cell cycle progression. It is also known as BASS1 (Bax antagonist selected in saccharomyces 1) or NRE-binding protein (Negative regulatory element-binding protein). The most common gene name of this splicing protein- which is only found in Humans (Homo sapiens)- is SON, but C21orf50, DBP5, KIAA1019 and NREBP can also be used as synonyms.〔(【引用サイトリンク】 Protein SON )〕 The protein encoded by SON gene binds to a specific DNA sequence upstream of the upstream regulatory sequence of the core promoter and second enhancer of human hepatitis B virus (HBV). Through this binding, it represses HBV core promoter activity, transcription of HBV genes, and production of HBV virions. The protein shows sequence similarities with other DNA-binding structural proteins such as gallin, oncoproteins of the MYC family, and the oncoprotein MOS. It may also be involved in protecting cells from apoptosis and in pre-mRNA splicing.〔 == Structure == The sequence length of the SON protein consists in 2426 aminoacids and its sequence status is totally completed. Its molecular weight is 263,830 Daltons (Da) and its domain contains 8 types of repeats which are distributed in 3 regions. This protein is found in the 21st chromosome and is mostly located in Nucleus speckle. Its higher expression is seen in leukocyte and heart.〔〔(【引用サイトリンク】 url = http://www.mybiosource.com/datasheet.php?products_id=427489 )〕 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「SON (gene)」の詳細全文を読む スポンサード リンク
