Ribosomal protein l19; rpl19
The ribosome is the only organelle conserved between prokaryotes and eukaryotes. In eukaryotes, this organelle consists of a 60S large subunit and a 40S small subunit. The mammalian ribosome contains 4 species of RNA (see 180450) and approximately 80 different ribosomal proteins, most of which appear to be present in equimolar amounts. In mammalian cells, ribosomal proteins can account for up to 15% of the total cellular protein, and the expression of the different ribosomal protein genes, which can account for up to 7 to 9% of the total cellular mRNAs, is coordinately regulated to meet the cell's varying requirements for protein synthesis. The mammalian ribosomal protein genes are members of multigene families, most of which are composed of multiple processed pseudogenes and a single functional intron-containing gene. The presence of multiple pseudogenes hampered the isolation and study of the functional ribosomal protein genes. By study of somatic cell hybrids, Nakamichi et al. (1986) had found that DNA sequences complementary to 6 mammalian ribosomal protein cDNAs could be assigned to chromosomes 5, 8, and 17. Ten fragments mapped to 3 chromosomes. These are probably a mixture of functional (expressed) genes and pseudogenes. One that maps to 5q23-q33 rescues Chinese hamster emetine-resistance mutations in interspecies hybrids and is therefore the transcriptionally active RPS14 gene (130620). Davies et al. (1989) described a PCR-based strategy for the detection of intron-containing genes in the presence of multiple pseudogenes. Feo et al. (1992) used this technique to identify the intron-containing PCR products of 7 human ribosomal protein genes and to map their chromosomal locations by hybridization to human/rodent somatic cell hybrids. All 7 ribosomal protein genes were found to be on different chromosomes: RPL19 on 17p12-q11; RPL30 (180467) on 8; RPL35A (180468) on 18; RPL36A (180469) on 14; RPS6 (180460) on 9pter-p13; RPS11 (180471) on 19cen-qter; and RPS17 (180472) on 11pter-p13. These are also different sites from the chromosomal location of previously mapped ribosomal protein genes S14 on chromosome 5 (130620), S4 on Xq and Yp (312760), and RPL7A on 9q3-q34 (185640). Davies and Fried (1995) used fluorescence in situ hybridization to position the RPL19 gene to 17q11. The wide distribution of the ribosomal protein genes throughout the human genome suggests that coordinate regulation of their expression in response to a cell's varying requirements for protein synthesis is not a result of cis-activation of chromosomal regions but is mediated by trans-acting factors. ...
