Genes affected
PTCD2 (HGNC:25734): (pentatricopeptide repeat domain 2) Enables RNA binding activity. Predicted to be involved in mitochondrion organization and regulation of mRNA processing. Predicted to act upstream of or within animal organ development; muscle cell development; and regulation of gene expression. Located in mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]
MRPS27 (HGNC:14512): (mitochondrial ribosomal protein S27) Mammalian mitochondrial ribosomal proteins are encoded by nuclear genes and help in protein synthesis within the mitochondrion. Mitochondrial ribosomes (mitoribosomes) consist of a small 28S subunit and a large 39S subunit. They have an estimated 75% protein to rRNA composition compared to prokaryotic ribosomes, where this ratio is reversed. Another difference between mammalian mitoribosomes and prokaryotic ribosomes is that the latter contain a 5S rRNA. Among different species, the proteins comprising the mitoribosome differ greatly in sequence, and sometimes in biochemical properties, which prevents easy recognition by sequence homology. This gene encodes a 28S subunit protein that may be a functional partner of the death associated protein 3 (DAP3). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2013]
