Given that imagery generation is more sensitive than storage to luminance, it is possible that the cognitive process implicated in storage is actually different to that during generation.
Cytoplasmic processing bodies or P-bodies are ribonucleoprotein aggregates that have been implicated in storage of mRNAs, translation repression, and mRNA degradation [ 20], another means of post-transcriptional regulation.
A class of proteins implicated in TAG storage and LD biogenesis are the mammalian FIT proteins [fat storage-inducing transmembrane proteins (Kadereit et al. 2008; Gross et al. 2010, 2011; Moir et al. 2012)], of which two orthologs exist in yeast, encoded by SCS3 and YFT2.
The frataxin-like homolog has been implicated in iron storage in other bacteria.
The Drosophila INDY gene encodes a related dicarboxylate transporter implicated in fat storage (Rogina et al., 2000).
SRSF2 is a well-known marker for nuclear speckles, nuclear domains implicated in the storage and supply of splicing factors to active transcription sites (Spector and Lamond, 2011).
High power electron micrographs revealed the presence of Lipid Whorls (LW) that are implicated in lysosomal storage disease and cholesterol accumulation [ 41] in degenerating neurons within the CA3 and subiculum of LAMP-2-deficient mice.
Although mboa- 7 affects PUFA incorporation into PI [ 18], dhs- 16 regulates dafachronic acids metabolism [ 50], and sptl- 1 is involved in the biosynthesis of ceramide [ 16], they have not been previously implicated in fat storage.
Many of these identified binding partners are localised, with SRSF2, to nuclear speckles, nuclear domains implicated in the storage, and supply of splicing factors to active transcription sites [ 30].
The chromatoid body contains abundant RNA binding proteins and has been implicated in the storage, metabolism, and cytoplasm-to-nuclear transport of mRNA, small RNA, and related proteins [ 78].
They form a ring structure in the absence of nucleotide, a form implicated in RadA storage in order to decrease ATP pool consuming [ 63] while the extended right-handed filament with AMP-PNP is suitable for ssDNA-binding and forming nucleoprotein filament [ 61].
