Cytoplasmic ribosomal proteins
Ribosomes are compositionally heterogeneous between species and even within the same cell, as evidenced by the existence of cytoplasmic and mitochondria ribosomes within the same eukaryotic cells. Certain researchers have suggested that heterogeneity in the composition of ribosomal proteins in mammals is important for gene regulation, i.e., the specialized ribosome hypothesis. However, this hypothesis is controversial and the topic of ongoing research. Webmost of the bacterial ribosomal proteins have counterparts in the human mitochondrial ribosome (Tables 1 and 2). However, homologues for the small subunit proteins S1, S3, …

The aggregation of αSyn is mainly formed in the cytoplasm, whereas some αSyn accumulation has also been found in the nuclei of neurons. To assess the effect of nuclear αSyn, we generated αSyn conjugated with a nuclear export signal (NES) or a …
WebJun 6, 2024 · These data support the notion that overall ribosome synthesis is not halted and that ample ribosomal proteins are present to drive ribosome production. Therefore, we conclude that α-sarcin activity does not impede nuclear export of pre-ribosomes. ... Alternatively, the components (e.g. r-proteins that assemble in the cytoplasm) that …
