MRPS2

Chr 9AR

mitochondrial ribosomal protein S2

Also known as: CGI-91, COXPD36, MRP-S2, S2mt, uS2m

The protein is required for mitoribosome formation and stability, and mitochondrial translation as a component of the small 28S mitochondrial ribosomal subunit. Mutations cause combined oxidative phosphorylation deficiency 36 through autosomal recessive inheritance. The pathogenic mechanism involves impaired mitochondrial protein synthesis leading to defective oxidative phosphorylation.
