60S ribosomal protein L7 (RPL7)

The protein contains 248 amino acids for an estimated molecular weight of 29226 Da.

 

Component of the large ribosomal subunit (PubMed:12962325). Binds to G-rich structures in 28S rRNA and in mRNAs. Plays a regulatory role in the translation apparatus; inhibits cell-free translation of mRNAs. (updated: Jan. 31, 2018)

Ribosomal protein l7; rpl7

The mammalian ribosome is composed of 4 RNA species (see 180450) and approximately 80 different proteins (see 180466). Meyuhas and Klein (1990) identified a transcriptionally active mouse Rpl7 gene. The 3.1-kb Rpl7 gene contains 7 exons and encodes an mRNA that is 897 nucleotides long. Seshadri et al. (1993) partially sequenced the human RPL7 gene and found that it shares many features with those of mouse Rpl7, including the position of the first intron and the polypyrimidine translation control element in the 5-prime noncoding region. By screening cDNA libraries derived from activated human T-lymphocyte cell lines with a mouse Rpl7 cDNA, Hemmerich et al. (1993) isolated human RPL7 cDNAs. The predicted 248-amino acid human RPL7 protein has an N-terminal basic leucine zipper (bZIP)-like domain and the RNP consensus submotif RNP2. The authors demonstrated that the N-terminal region of mammalian RPL7 proteins mediates RPL7 homodimerization and stable binding of RPL7 to DNA and RNA in vitro. They found that RPL7 preferentially binds to 28S rRNA and mRNA. Hemmerich et al. (1993) showed that mouse Rpl7 mRNA is induced upon activation of resting B and T lymphocytes. The RPL7 protein has been shown to be an autoantigen in patients with systemic lupus erythematosus (152700) and other systemic autoimmune diseases (Absi et al., 1989; von Mikecz et al., 1994; Neu et al., 1995; von Mikecz et al., 1995). Sapi et al. (1994) identified a processed pseudogene for ribosomal protein L7 (RPL7P) within intron 1 of the FMS gene (164770). This pseudogene was not actively transcribed. By somatic cell hybrid and radiation hybrid mapping analyses, Kenmochi et al. (1998) mapped the human RPL7 gene to 8q. ... More on the omim web site
