Predicted to be a structural constituent of ribosome. Predicted to be involved in mitochondrial transcription and positive regulation of transcription, DNA-templated. Predicted to act upstream of or within translation. Located in mitochondrion. Is expressed in several structures, including early conceptus; gonad; heart; liver; and metanephros. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 45. Orthologous to human MRPL12 (mitochondrial ribosomal protein L12).
