Predicted to enable rRNA binding activity. Predicted to be involved in several processes, including mitochondrial gene expression; mitochondrial large ribosomal subunit assembly; and posttranscriptional regulation of gene expression. Predicted to be located in mitochondrial nucleoid. Predicted to be active in mitochondrial matrix and ribonucleoprotein granule. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency. Orthologous to human FASTKD2 (FAST kinase domains 2). [provided by Alliance of Genome Resources, Apr 2022]
