TFE3B has several biochemical functions, for example, RNA polymerase II core promoter proximal region sequence-specific DNA binding, protein dimerization activity, transcriptional activator activity, RNA polymerase II core promoter proximal region sequence-specific binding. Some of the functions are cooperated with other proteins, some of the functions could acted by TFE3B itself. We selected most functions TFE3B had, and list some proteins which have the same functions with TFE3B. You can find most of the proteins on our site.
