FAMILY

mitochondrion-specific ribosomal protein mL64 family

DESCRIPTION

Also known as G45IP_HUMAN, GADD45GIP1, MRPL59, PLINP1, PRG6. Acts as a negative regulator of G1 to S cell cycle phase progression by inhibiting cyclin-dependent kinases. Inhibitory effects are additive with GADD45 proteins but occurs also in the absence of GADD45 proteins. Acts as a repressor of the orphan nuclear receptor NR4A1 by inhibiting AB domain-mediated transcriptional activity. May be involved in the hormone-mediated regulation of NR4A1 transcriptional activity. May play a role in mitochondrial protein synthesis. Component of the mitochondrial large ribosomal subunit (mt-LSU) (PubMed:28892042, PubMed:25838379, PubMed:25278503). Mature mammalian 55S mitochondrial ribosomes consist of a small (28S) and a large (39S) subunit. The 28S small subunit contains a 12S ribosomal RNA (12S mt-rRNA) and 30 different proteins. The 39S large subunit contains a 16S rRNA (16S mt-rRNA), a copy of mitochondrial valine transfer RNA (mt-tRNA(Val)), which plays an integral structural role, and 52 different proteins (PubMed:23908630, PubMed:25278503, PubMed:25838379). Interacts with GADD45A, GADD45B and GADD45G (PubMed:12716909). Interacts with NR4A1 via the NR4A1 AB domain (PubMed:15459248). Interacts with ATAD3A and ATAD3B (PubMed:22453275).
