(A) Select example Lh VLP proteins, many of which
are expected to be membrane-associated via integral or other biochemical
mechanisms, are displayed by their proteomic Classes 1 – 3 (bulleted
within descriptive subclasses). Example subclasses and individual proteins found
in enrichment analyses (B, C) are shown in red. AGT =
anterograde transport; RGT = retrograde transport. (B, C)
Enrichments from Vesiclepedia: The organelle character of Lh
VLPs based on GO Terms of predicted orthologs is (B) significant
and (C) highly enriched. (B) Among VLP proteins with
annotated orthologs, 71% are mitochondrial, of which 12% are
localized to the mitochondrial inner membrane. Approximately 50% of
conserved sequences in the proteome are common to microvesicles/exosomes.
(C) Vesicular and mitochondrial, including that of the caspase
complex, terms are the most over-represented. Furthermore, genes within the GO
Term (GO:0008303) for pro-apoptotic caspase complexes were more than 200 times
over-represented. (See also
