Summaries
Gene Group (FlyBase)
CYTOPLASMIC SMALL RIBOSOMAL PROTEINS -
Cytoplasmic ribosomes are found on the endoplasmic reticulum and in the cytoplasm. 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 small subunit is to bind mRNA. (Adapted from FBrf0205398)
UBIQUITIN -
Ubiquitin is a small (76 amino acid), highly conserved protein found in all eukaryotes. Through its covalent attachment to other proteins, ubiquitin can modify protein activity in numerous ways. The most well known is the targeting of proteins for proteasomal degradation. Ubiquitin is often expressed as a fusion protein, either as polyubiquitin or fused with the ribosomal proteins L40 and S27a. Ubiquitin monomers are generated by post-translational cleavage. (Adapted from PMID:12729753 and PMID:27012465)
Phenotypic Description (Red Book; Lindsley and Zimm 1992)
mfs(2)31: male-female-sterile (2) in region 31
Homozygotes have short thin bristles; relative viability 25% at 25; hemizygotes lethal. Both males and females sterile at 25 but some fertility observed in flies raised at 23. Males raised at 28.5 have no motile sperm and some spermatids have micronuclei, and occasionally two basal bodies and axonemes are observed.
Ubi-m: Ubiquitin-monomeric
Structural gene for ubiquitin (Lee et al., 1988). Ubi-m codes for a fusion protein whose single ubiquitin sequence is attached to a tail polypeptide with 65% identity to the yeast ubiquitin tail protein and 82% identity to the human ubiquitin tail protein. Ubiquitin-monomeric is not inducible by heat shock.

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.

          Likely Minute gene.

          Deletions removing RpS27A but no other cytoplasmic ribosomal protein-encoding genes show Minute phenotypes.

          RpS27A and Ip259 share a 5' untranslated exon, however, alternative splicing produces two structurally unrelated proteins which do not share any common sequences.

          The genomic organisation of the RpS27A locus has been characterised.

          Antibody staining of polytene chromosomes shows that ubiquitin is mainly associated with the compact and stabilized structure that forms the bands rather than with the more decondensed and destabilized protein-DNA structure that forms interbands and puffs.

          Four (unnamed) recessive lethal alleles have been isolated during a cytogenetic analysis of chromosomal region 31.

          RpS27A expression has been studied in heat shocked aging flies.

          Recessive alleles suppress position-effect variegation of In(1)wm4 when homozygous. The suppressor phenotypes are sexually dimorphic.

          Structural gene for ubiquitin (Lee et al., 1988). Ubi-f80 codes for a fusion protein whose single ubiquitin sequence is attached to a tail polypeptide with 65% identity to the yeast ubiquitin tail protein and 82% identity to the human ubiquitin tail protein. Ubiquitin-monomeric is not inducible by heat shock.

          Additional comments

          "RpS27A" likely corresponds to "M(2)31E".

          One or more of the processed transcripts for this gene share(s) untranslated sequences with a transcript of an adjacent gene, but encode(s) a single open reading frame (ORF). The non-overlapping ORFs that share untranslated sequences are represented by RpS27A and Ip259.

          NCBI Gene - Gene integrates information from a wide range of species. A record may include nomenclature, Reference Sequences (RefSeqs), maps, pathways, variations, phenotypes, and links to genome-, phenotype-, and locus-specific resources worldwide.
          GenBank Nucleotide - A collection of sequences from several sources, including GenBank, RefSeq, TPA, and PDB.
          GenBank Protein - A collection of sequences from several sources, including translations from annotated coding regions in GenBank, RefSeq and TPA, as well as records from SwissProt, PIR, PRF, and PDB.
          RefSeq - A comprehensive, integrated, non-redundant, well-annotated set of reference sequences including genomic, transcript, and protein.
          UniProt/GCRP - The gene-centric reference proteome (GCRP) provides a 1:1 mapping between genes and UniProt accessions in which a single 'canonical' isoform represents the product(s) of each protein-coding gene.
