UniProt functional annotation for P32905

UniProt code: P32905.

Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast).
Taxonomy: Eukaryota; Fungi; Dikarya; Ascomycota; Saccharomycotina; Saccharomycetes; Saccharomycetales; Saccharomycetaceae; Saccharomyces.
 
Function: Required for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA- precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits.
 
Subunit: Component of the small ribosomal subunit. Mature ribosomes consist of a small (40S) and a large (60S) subunit. The 40S subunit contains 32 different proteins (encoded by 56 genes) and 1 molecule of RNA (18S). The 60S subunit contains 46 different proteins (encoded by 81 genes) and 3 molecules of RNA (25S, 5.8S and 5S).
Subcellular location: Cytoplasm.
Ptm: N-terminally acetylated by acetyltransferase NatA.
Disruption phenotype: Reduction in growth rate, a decrease in free 40S subunits, an increase in the amount of free 60S subunits and a decrease in polysome size.
Miscellaneous: Present with 93700 molecules/cell in log phase SD medium.
Miscellaneous: There are 2 genes for S0 in yeast.
Miscellaneous: This protein appears to have acquired a second function as a laminin receptor specifically in the vertebrate lineage. This protein does not bind laminin.
Similarity: Belongs to the ribosomal protein S2P family.
