| [[http://www.uniprot.org/uniprot/RM14_HUMAN RM14_HUMAN]] Forms part of 2 intersubunit bridges in the assembled ribosome. Upon binding to MALSU1 intersubunit bridge formation is blocked, preventing ribosome formation and repressing translation (Probable).<ref>PMID:22829778</ref> [[http://www.uniprot.org/uniprot/G45IP_HUMAN G45IP_HUMAN]] 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. [[http://www.uniprot.org/uniprot/RM36_HUMAN RM36_HUMAN]] Component of the large subunit of the mitochondrial ribosome. [[http://www.uniprot.org/uniprot/RM16_HUMAN RM16_HUMAN]] Component of the large subunit of mitochondrial ribosome. [[http://www.uniprot.org/uniprot/ICT1_HUMAN ICT1_HUMAN]] Essential peptidyl-tRNA hydrolase component of the mitochondrial large ribosomal subunit. Acts as a codon-independent translation release factor that has lost all stop codon specificity and directs the termination of translation in mitochondrion, possibly in case of abortive elongation. May be involved in the hydrolysis of peptidyl-tRNAs that have been prematurely terminated and thus in the recycling of stalled mitochondrial ribosomes.<ref>PMID:20186120</ref> [[http://www.uniprot.org/uniprot/RM41_HUMAN RM41_HUMAN]] Component of the mitochondrial ribosome large subunit. Also involved in apoptosis and cell cycle. Enhances p53/TP53 stability, thereby contributing to p53/TP53-induced apoptosis in response to growth-inhibitory condition. Enhances p53/TP53 translocation to the mitochondria. Has the ability to arrest the cell cycle at the G1 phase, possibly by stabilizing the CDKN1A and CDKN1B (p27Kip1) proteins.<ref>PMID:16024796</ref> <ref>PMID:16256947</ref> [[http://www.uniprot.org/uniprot/RM44_HUMAN RM44_HUMAN]] Component of the 39S subunit of mitochondrial ribosome. May have a function in the assembly/stability of nascent mitochondrial polypeptides exiting the ribosome.<ref>PMID:23315540</ref> | | [https://www.uniprot.org/uniprot/RM02_HUMAN RM02_HUMAN] |
