NOP1 / YDL014W Phenotype

Phenotype annotations for a gene are curated single mutant phenotypes that require an observable (e.g., "cell shape"), a qualifier (e.g., "abnormal"), a mutant type (e.g., null), strain background, and a reference. In addition, annotations are classified as classical genetics or high-throughput (e.g., large scale survey, systematic mutation set). Whenever possible, allele information and additional details are provided.


Summary
Essential gene; repression leads to reduced levels of pre-rRNA species, increased accumulation of snRNAs and defects in small ribosomal subunits biogenesis; overexpression causes G1 phase delay and slow growth

Annotations

A phenotype is defined as an observable (e.g., apoptosis) and a qualifier (e.g., increased). There may be more than one row with the same phenotype if that phenotype was observed in separate studies or in different conditions, strains, alleles, etc.

Shared Phenotypes

This diagram displays phenotype observables (purple squares) that are shared between the given gene (yellow circle) and other genes (gray circles) based on the number of phenotype observables shared (adjustable using the slider at the bottom).


Reset

Click on a gene or phenotype observable name to go to its specific page within SGD; drag any of the gene or observable objects around within the visualization for easier viewing; click “Reset” to automatically redraw the diagram; filter the genes that share observable terms with the given gene by the number of terms they share by clicking anywhere on the slider bar or dragging the tab to the desired filter number.
