... without mitochondria. If they were to do that, they'd probably use Bax or Bak as enzyme linked receptors to kick of a MAP kinase phosphorylation cascade to signal it.

... genes were implicated in aggressive behavior (http://jhered.oxfordjournals.org/content/95/3/185.full). Considering that receptor is part of the cascade signaling mechanism there is good possibility of recessive allele activating/deactivating a totally different subset of downstream genes that ...

... and then dialyse the hell out of if your protein is smaller than the MBP it or use a selection of Amicon filters (or something similar) in cascade to 1st get your protein in the eluate, and then wash it up in a filter that would keep the protein the saved fraction.

... mechanisms in any way enhance or modulate the innate (non-specific) immune system? I was thinking that it does by way of the classical complement cascade with antibodies (which I believe are adaptive immunological mechanisms) opsonising antigens for digestion by phagocytes (innate immune modulators). ...

... occurs, antibody–antigen complexes form and these activate complement proteins. The activation of one kind of complement protein results in a cascade effect where each activated complement protein then activates another, and so on down the chain.
