title: Nucleolar and cytoplasmic localization of annexin V.
abstract: The subcellular localization of annexin V in cultured human umbilical vein endothelial cells, epithelial cells and fibroblasts was examined. Indirect immunofluorescence and immunoblotting studies using affinity-purified anti-annexin V antibodies revealed that annexin V is located within the cytoplasm and nucleus of these cells. Further examination and direct binding studies showed that annexin V within the nucleus is associated with the nucleolus. These findings suggest that annexin V may play a role in a nucleolar function, such as ribosome assembly and transport.
