Situation 1. If it was agreed to obsolete the cell fraction terms

a. Remove any annotation that is duplicated by an in vivo CC location (see rules for individual terms below)

b. Remaining annotations would be mapped to an equivalent CC term (following suggestions below) N.B. UniProtKB has only 64 EXP-annotations and 27 NAS/TAS-annotations to cell fraction or children, that are not duplicated by an in vivo CC location

c. Remove ISS and Ensembl Compara IEA predictions.

Situation 2. If the cell fraction terms were not obsoleted

1. Only allow EXP-level annotations to cell fraction and children in future. Discourage use of such terms in general, encourage use of the 'mapped' terms instead.

2. Remove any ISS or any IEAs from Ensembl Compara

3. Remove/disallow manual annotation to cell fraction/children where:

Annotations to CELL FRACTION. Remove if any other CC annotation. Remaining annotations map to GO:cell part

Annotations to SOLUBLE FRACTION. Remove if any other CC annotation. Remaining annotations map to GO:cell part

Annotations to INSOLUBLE FRACTION. Remove if any other CC annotation. Remaining annotations map to GO:cell part

Annotations to PLASMA MEMBRANE ENRICHED FRACTION. Remove if EXP-level annotations for GO:0005886 plasma membrane or children. Remaining annotations map to GO:plasma membrane

Annotations to INTEGRAL TO MEMBRANE OF MEMBRANE FRACTION. Remove if EXP-level annotations for GO:0016021 integral to plasma membrane or children. Remaining annotations map to GO:integral to membrane

Annotations to PERIPHERAL TO MEMBRANE OF MEMBRANE FRACTION. Remove if EXP-level annotations for GO:0019898 extrinsic to membrane or children. Remaining annotations map to GO:extrinsic to membrane

Annotations to SYNAPTOSOME. Remove if EXP-level annotations for GO:0043005 neuron projection or children Remaining annotations map to GO:neuron projection

Annotations to VESICULAR FRACTION. Remove if EXP-level annotations for GO:0031982 vesicle or children. Remaining annotations map to GO:vesicle

Annotations to MICROSOME. Remove if EXP-level annotations for GO:0043231 intracellular membrane-bounded organelle or children. Remaining annotations map to GO:intracellular membrane-bounded organelle

Annotations to ROUGH MICROSOME. Remove if EXP-level annotations for rough endoplasmic reticulum or children. Remaining annotations map to GO:rough ER

Annotations to SMOOTH MICROSOME. Remove if EXP-level annotations for smooth endoplasmic reticulum or children. Remaining annotations map to GO:smooth ER

Annotations to HOST CELL MICROSOME. Remove if EXP-level annotations for host cell intracellular membrane-bounded organelle or children. Remaining annotations map to GO:host cell intracellular membrane-bounded organelle


UniProt controlled vocabularies2GO

There are: 411 IEA UniProt Keyword annotations (169 to Swiss-Prot entries)

1326 IEA UniProt Subcellular Location annotations (1035 to Swiss-Prot entries)

Consider mapping these to the equivalent terms as shown below;

UniProt vocabulary -> GO term

microsome -> GO:intracellular membrane-bounded organelle

microsome membrane -> GO:organelle membrane (currently mapped to GO:microsome)

host microsome -> GO:host cell intracellular membrane-bounded organelle

host microsome membrane -> GO: host cell intracellular membrane-bounded organelle (currently mapped to GO:host cell microsome)

transmembrane -> GO:integral to membrane (currently mapped to GO:membrane fraction)

synaptosome -> GO:neuron projection
