# WARNINGS - THE FOLLOWING HAVE BEEN REMOVED FOR THE REASONS NOTED
## Annotations that have been removed.
20141113: Eukaryota_PTN000520141 to ribosomal large subunit biogenesis (GO:0042273)  using [SGD:S000006373] - lacks supporting evidence

# NOTES
NOTE: NOT "spliceosome" annotations for mouse Prpf19 are specifically for the beta isoform (Q99KP6-2). The canonical isoform Q99KP6-1 IS part of the spliceosome.

# 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).
