Gene Group (FlyBase)
CYTOPLASMIC SMALL 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 small subunit is to bind mRNA. (Adapted from FBrf0205398.)
CYTOPLASMIC SMALL 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 small subunit is to bind mRNA. Tissue expression data from modENCODE has been used to infer the composition of the cytosolic small ribosomal subunit testis-specific variant. (Adapted from FBrf0205398.)

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.

      A deletion that removes RpS25 and RpL3 but no other cytoplasmic ribosomal protein-encoding genes shows Minute phenotypes, whereas molecularly-defined mutations in RpL3 do not result in Minute phenotypes. This suggests that RpS25 is a Minute gene.

      The M(3)86D mutant phenotype is not suppressed by RpL32+t3.3.

      One of a class of genes (see MIN record) that when present in one, rather than two, copies, produce a characteristic phenotype consisting of short slender bristles and delayed development.

      One of a class of genes (see MIN record) that when present in one, rather than two, copies, produce a characteristic phenotype consisting of short slender bristles and delayed development. Identified by virtue of Minute phenotype of Df(3R)M86D; This Minute erroneously designated M(3)S35 (Lindsley et al., 1972).

      Relationship to Other Genes

      Source for merge of: RpS25 M(3)S32 M(3)86D

      Additional comments

      "RpS25" likely corresponds to "M(3)86D".

      Mapping against deficiencies in 86D suggests M(3)86D may correspond to RpL3 and/or RpS25.
