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)
Protein Function (UniProtKB)
May be an associated component of the ribosome rather than a core structural subunit. May act as a translation initiation factor. Has a role in regulation of cell proliferation in the hematopoietic organs and the imaginal disks of larva.

        Minute gene.
        (Marygold et al., 2007)
        Deletions removing oho23B but no other cytoplasmic ribosomal protein-encoding genes show Minute phenotypes.
        (Marygold et al., 2007)
        Molecularly-defined mutations in oho23B result in Minute phenotypes.
        (Marygold et al., 2007)
        oho23B acts as a translation initiation factor, rather than as a core ribosomal protein.
