Protein function (UniProt)

DNA-binding protein SMUBP-2

5' to 3' helicase that unwinds both RNA and DNA duplexes in an ATP-dependent reaction (Probable) (PubMed:19158098, PubMed:30218034). Specific to 5'-phosphorylated single-stranded guanine-rich sequences (PubMed:22999958, PubMed:8349627). May play a role in RNA metabolism, ribosome biogenesis or initiation of translation (PubMed:19158098, PubMed:19299493). May play a role in regulation of transcription (By similarity). Interacts with tRNA-Tyr (PubMed:19299493). Has low processivity (PubMed:30218034)
