ID3(分化抑制因子3,Inhibitor of Differentiation 3),正式名稱爲「inhibitor of DNA binding 3, HLH protein」(DNA結合抑制因子3,HLH(螺旋-環-螺旋)蛋白)。人ID3蛋白由ID3基因編碼[5][6]

功能

分化抑制因子(ID)家族螺旋-環-螺旋(HLH)蛋白質缺乏基因的DNA結合結構域。它通過與其他的HLH蛋白形成異二聚體,阻止其與DNA結合,進而抑制其功能[6]

相互作用

ID3能與TCF3英语TCF3(轉錄因子3)發生相互作用[7][8]

ID3的抑制劑

BTG2英语BTG2能與ID3基因的啓動子結合,進而抑制其ID3基因的活性。如果敲除海馬的BTG2基因的話,海馬ID3表達就會上調,進而使其神經元無法發生末端分化[9]
