General Information
Term pigment granule ID (Ontology) FBbt:00004234 (Fly Anatomy)
Definition A small, subcellular membrane-bounded vesicle containing pigment and/or pigment precursor molecules. Pigment granule biogenesis is poorly understood, as pigment granules are derived from multiple sources including the endoplasmic reticulum, coated vesicles, lysosomes, and endosomes.
