UniProt IDQ9NUL7
Primary gene name(s)DDX28
Synonym gene name(s)MDDX28
Protein nameProbable ATP-dependent RNA helicase DDX28
Protein functionPlays an essential role in facilitating the proper assembly of the mitochondrial large ribosomal subunit and its helicase activity is essential for this function, PubMed:25683708, PubMed:25683715. May be involved in RNA processing or transport. Has RNA and Mg(2+-dependent ATPase activity, PubMed:11350955. {ECO:0000269|PubMed:11350955, ECO:0000269|PubMed:25683708, ECO:0000269|PubMed:25683715}.
Subcellular locationNucleus {ECO:0000269|PubMed:11350955, ECO:0000269|PubMed:25683708}. Mitochondrion {ECO:0000269|PubMed:11350955}. Mitochondrion matrix, mitochondrion nucleoid {ECO:0000269|PubMed:25683715}. Mitochondrion matrix {ECO:0000269|PubMed:25683708}. Note=Transported between these two compartments. Nuclear localization depends on active RNA polymerase II transcription. Localizes to mitochondrial RNA granules found in close proximity to the mitochondrial nucleoids. {ECO:0000269|PubMed:25683708, ECO:0000269|PubMed:25683715}.
