  Function in Host
Binds to scaffold/matrix attachment region (S/MAR) DNA andforms a molecular assembly point to allow the formation of a'transcriptosomal' complex (consisting of SR proteins and RNApolymerase II) coupling transcription and RNA processing. Functions as an estrogen receptor corepressor and canalso bind to the HSP27 promoter and decrease its transcription. Thereby acts as a negative regulator of cellproliferation. When associated with RBMX, binds toand stimulates transcription from the SREBF1 promoter. [1-2]
