Ribosomal protein s9; rps9
The mammalian ribosome is a macromolecular assembly of 4 RNA species (see 180450) and approximately 80 different proteins. By searching sequence databases with the partial sequences of randomly selected cDNAs from a human colorectal cDNA library, Frigerio et al. (1995) identified cDNAs encoding homologs of rat ribosomal proteins S5 (RPS5; 603630), S9 (RPS9), S10 (RPS10; 603632), S29 (RPS29; 603633), L5 (RPL5; 603634), L21 (RPL21; 603636), L27a (RPL27A; 603637), and L28 (RPL28; 603638). Frigerio et al. (1995) completed the cDNA sequences of these human ribosomal proteins. The deduced 194-amino acid human RPS9 differs from rat Rps9 by 5 amino acids. Northern blot analysis suggested variable expression of RPS9 in colorectal cancers compared to adjacent normal tissues, although no correlation between the level of expression and the severity of the disease was found. By somatic cell hybrid and radiation hybrid mapping analyses, Kenmochi et al. (1998) mapped the human RPS9 gene to 19q13.4 (GenBank GENBANK AB007150). ... More on the omim web site
