WebThe cytoplasmic 40S pre-ribosome now contains ribosomal proteins, the 20s rRNA and a few non-ribosomal factors. The final formation of the 40S subunit “beak” structure occurs … WebProteomic analysis identified Serbp1 in the cytoplasmic ribosomes of the rodent testis. Polysome profiling suggested that Serbp1, as a component of the small 40S subunit, was included in translating ribosomes (polysomes). Cosedimentation of Serbp1 with the 40S subunit was observed after dissociation of the ribosomal subunits.
