In neuronal ceroid lipofuscinoses, types 2, 3, 4 and 8, the main population of storage granules was devoid of ubiquitination.
In fact, platelet secretion occurs from three distinct populations of storage granules (each releasing unique messenger molecules) as well as on-demand manufacture of bioactive lipid species.
Activation also triggers the release of storage granules and increased exposure of GP IIb/IIIa, furthering the attachment of additional platelets.
In addition to causing platelet shape change and aggregation, collagen and thrombin promote secretion by platelets of the contents of storage granules which include ADP and ATP.
One such helicase (DOZI, a homolog of human DDX6 and yeast Dhh1) is essential to the development of the zygote in infected mosquitoes, and traffics a substantial portion of the mRNA pool to storage granules [ 12, 34, 35].
Furthermore, there was evidence of degranulation of arginase storage granules.
Were these particles to be the delivery mechanism for at least part of the inhaled red tide brevetoxins, then it could be concluded that any toxin or metabolite present in the organism has the potential to be inhaled perhaps as part of an intracellular storage granule or organelle.
(B ) Cell containing two cytoplasmic clusters located next to storage granules.
Encystment involves a multi-stage developmental process that includes the rounding of cells, production of large intracellular storage granules of poly-hydroxybutyrate (PHB) and the excretion of a protective exopolysaccharide coating that envelops dormant cysts.
Here, we summarize our knowledge about the enigmatic structure of proteasome storage granules and the trafficking of proteasomes and their substrates between the cyto- and nucleoplasm.
