20110207: cellular organisms_PTN000161291 is found in cytosolic small ribosomal subunit (GO:0022627) 

# biological_process
20110207: cellular organisms_PTN000161291 participates in rRNA processing (GO:0006364) 
20110207: cellular organisms_PTN000161291 participates in ribosomal small subunit biogenesis (GO:0042274) 

# WARNINGS - THE FOLLOWING HAVE BEEN REMOVED FOR THE REASONS NOTED

# NOTES
MF
Did not propagate GO:3735 structural consituent of ribosome term because that concept is already captured by the CC term.
BP
Propagated both GO:6364, rRNA processing and GO:42274 ribosome small subunit biogenesis terms. Did not propagate ribosome assembly because based on the evidence it seems like there is a defect in generating the subunits than in the process of assembly.

# REFERENCE
Annotation inferences using phylogenetic trees
The goal of the GO Reference Genome Project, described in PMID 19578431, is to provide accurate, complete and consistent GO annotations for all genes in twelve model organism genomes. To this end, GO curators are annotating evolutionary trees from the PANTHER database with GO terms describing molecular function, biological process and cellular component. GO terms based on experimental data from the scientific literature are used to annotate ancestral genes in the phylogenetic tree by sequence similarity (ISS), and unannotated descendants of these ancestral genes are inferred to have inherited these same GO annotations by descent. The annotations are done using a tool called PAINT (Phylogenetic Annotation and INference Tool).
