Protein Information (annotations from UniProt)

Database IDHIV0001225
UniProt IDQ12849
Primary gene name(s)GRSF1
Synonym gene name(s)unknown
Protein nameG-rich sequence factor 1
Protein functionRegulator of post-transcriptional mitochondrial gene expression, required for assembly of the mitochondrial ribosome and for recruitment of mRNA and lncRNA. Binds RNAs containing the 14 base G-rich element. Preferentially binds RNAs transcribed from three contiguous genes on the light strand of mtDNA, the ND6 mRNA, and the long non-coding RNAs for MT-CYB and MT-ND5, each of which contains multiple consensus binding sequences. {ECO:0000269|PubMed:23473033, ECO:0000269|PubMed:23473034}.
Subcellular locationCytoplasm. Mitochondrion matrix, mitochondrion nucleoid {ECO:0000269|PubMed:25683715}. Note=Localizes to mitochondrial RNA granules found in close proximity to the mitochondrial nucleoids. {ECO:0000269|PubMed:25683715}.
