Gene Snapshot
Ribosomal protein L13 (RpL13) encodes a ribosomal structural constituent. [Date last reviewed: 2019-07-11]
Gene Group (FlyBase)
CYTOPLASMIC LARGE RIBOSOMAL SUBUNIT -
Cytoplasmic ribosomes are found on the endoplasmic reticulum and in the cytosol. They translate all mRNAs produced from nuclear genes and perform the majority of cellular protein synthesis. Ribosomes are formed by two ribonucleoprotein subunits, large and small. The principle function of the large subunit is to bind tRNA during the synthesis of polypeptides. (Adapted from FBrf0205398.)
CYTOPLASMIC LARGE RIBOSOMAL SUBUNIT - TESTIS-SPECIFIC VARIANT -
Cytoplasmic ribosomes are found on the endoplasmic reticulum and in the cytosol. They translate all mRNAs produced from nuclear genes and perform the majority of cellular protein synthesis. Ribosomes are formed by two ribonucleoprotein subunits, large and small. The principle function of the large subunit is to bind tRNA during the synthesis of polypeptides. Tissue expression data from modENCODE has been used to infer the composition of the cytosolic large ribosomal subunit testis-specific variant. (Adapted from FBrf0205398.)
Protein Function (UniProtKB)
Component of the ribosome, a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23636399). The small ribosomal subunit (SSU) binds messenger RNAs (mRNAs) and translates the encoded message by selecting cognate aminoacyl-transfer RNA (tRNA) molecules (Probable). The large subunit (LSU) contains the ribosomal catalytic site termed the peptidyl transferase center (PTC), which catalyzes the formation of peptide bonds, thereby polymerizing the amino acids delivered by tRNAs into a polypeptide chain (Probable). The nascent polypeptides leave the ribosome through a tunnel in the LSU and interact with protein factors that function in enzymatic processing, targeting, and the membrane insertion of nascent chains at the exit of the ribosomal tunnel (Probable). As part of the LSU, it is probably required for its formation and the maturation of rRNAs (Probable).

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

      Haploinsufficient locus.

      RNAi screen using dsRNA made from templates generated with primers directed against this gene results in aberrantly short, monopolar spindles when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA.

      Minute gene.

      Deletions removing RpL13 but no other cytoplasmic ribosomal protein-encoding genes show Minute phenotypes. The interval between flanking non-Minute deletions contains only RpL13.

      dsRNA made from templates generated with primers directed against RpL13 that is transfected into S2 treated with Listeria monocytogenes reveals RpL13 to be involved in Listeria monocytogenes vacuolar escape.

      The level of identity between RpL13 and the human BBC1 gene demonstrates the gene has been highly conserved throughout eukaryotic evolution. RpL13 is highly expressed during embryonic development and may have a role in the cell, possible nuclear and growth related.

      Additional comments

      The genetically defined "M(2)31A" locus (characterized by previous aneuploidy analyses) likely comprises two separable, closely linked Minute genes ("RpL7" and "RpL13").
