Expression profile of mouse Mterfd2, a novel component of the mitochondrial transcription termination factor (MTERF) family.
Mterfd2 is a component of mitochondria transcription termination factor (MTERF) family which belongs to the MTERF4 subfamily. In this report, we characterized the expression profile of mouse Mterfd2 during embryogenesis by in situ hybridization (ISH), quantitative real-time PCR (qRT-PCR) and northern blot. The whole mount ISH at E9.5, E10.5 and E11.5 showed that Mterfd2 was dynamically expressed in the brain. Besides, at E9.5 and E10.5 stages, Mterfd2 was persistently expressed in the lateral plate mesoderm and heart; at E10.5 and E11.5 stages, it showed an abundant expression in the limb buds. The tissue ISH of E13.5 and E15.5 suggested that Mterfd2 was ubiquitously expressed, and has the higher expression in the forebrain, diencephalon, midbrain, spinal cord, dorsal root ganglion, tongue, lung, liver and kidney. This ubiquitous expression profile in the late embryogenesis was further confirmed by qRT-PCR and northern blot at E12.5, E15.5 and E18.5 stages. Besides, the results of co-location of EGFP-Mterfd2 fusion protein indicated that Mterfd2 was targeted to the mitochondria. Collectively, these data suggested that Mterfd2 showed a dynamic expression pattern during embryogenesis. It might play an important role in the organ differentiation which was probably resulted from its role in the mitochondrial transcription regulation.
