DESCRIPTION

Also known as SMBP2_HUMAN, IGHMBP2, SMBP2, SMUBP2. 5' to 3' helicase that unwinds RNA and DNA duplices in an ATP-dependent reaction. Acts as a transcription regulator. Required for the transcriptional activation of the flounder liver-type antifreeze protein gene. Exhibits strong binding specificity to the enhancer element B of the flounder antifreeze protein gene intron. Binds to the insulin II gene RIPE3B enhancer region. May be involved in translation (By similarity). DNA-binding protein specific to 5'-phosphorylated single-stranded guanine-rich sequence related to the immunoglobulin mu chain switch region. Preferentially binds to the 5'-GGGCT-3' motif. Interacts with tRNA-Tyr. Stimulates the transcription of the human neurotropic virus JCV. Homooligomer. Interacts with RUVBL1, RUVBL2, GTF3C1 and ABT1. Is part of large cytosolic ribonucleoprotein complexes (Probable). Associates with the ribosomes.
