- cyanosome
A tissue-specific, membrane-bounded cytoplasmic organelle within which an unknown blue pigment is localized. Cyanosomes are synthesized in cyanophores and are blue in appearance.
- Cul4B-RING E3 ubiquitin ligase complex
A ubiquitin ligase complex in which a cullin from the Cul4B subfamily and a RING domain protein form the catalytic core; substrate specificity is conferred by unknown subunits.
- inositol-1,3,4,5,6-pentakisphosphate kinase activity
Catalysis of the reaction: ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate = ADP + diphospho-1D-myo-inositol tetrakisphosphate. The isomeric configuration of diphospho-1D-myo-inositol tetrakisphosphate is unknown.
- median body
A non-membrane bound, semi-organized microtubule array of unknown function found in Giardia species (trophozoite stage). It is located on the dorsal side of the trophozoite, slightly posterior to the ventral disc.
- inositol hexakisphosphate kinase activity
Catalysis of the reaction: ATP + 1D-myo-inositol 1,2,3,4,5,6-hexakisphosphate = ADP + diphospho-1D-myo-inositol-pentakisphosphate. The isomeric configuration of diphospho-1D-myo-inositol-pentakisphosphate (PP-IP5) is unknown.
- obsolete inositol hexakisphosphate kinase activity
OBSOLETE. Catalysis of the reactions: ATP + 1D-myo-inositol hexakisphosphate = ADP + 5-diphospho-1D-myo-inositol (1,2,3,4,6)pentakisphosphate, and ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate = ADP + diphospho-1D-myo-inositol tetrakisphosphate (isomeric configuration unknown).
- obsolete unlocalized protein complex
OBSOLETE. Used as a holding place for cellular components whose precise localization is, as yet, unknown, or has not been determined by GO (the latter is the major reason for nodes to have this parent); this term should not be used for annotation of gene products.
