I suppose my interest would most readily align with that of the topic creator. What I want to study can be summed up as any property of a biological system that cannot or will not be observed when the small constitutive agent is observed. I feel that these phenomena represent a new fundamental level in biology; that is to say, they are not readily described by the context (like so much else in biology) but rely on the nature of the interaction between the agents rather than the proteins involved. While I do think it's important to study such proteins, so much in biology (as I said in another topic) has become "what protein binds to that? oh, protein Z? alright. What protein binds to this? ah, protein L. What protein binds to..." etc etc, essentially characterizing organisms rather than elucidating anything that can be called paradigmatic.
Certain things, (neurons being the canonical example) like the microorganisms in the Dictiostelida and Myxococcus genuses exhibit astonishing self-organization that results in new behavior that can't be easily explained by looking at a single agent (i.e., a single bacterium). This of course goes far beyond biology and has pretty big implications for stuff like information, systems, and control theory but is probably best exemplified by biology.
I'm also really interested in the reform of evolutionary theory and how it applies to the philosophy of science. You may have guessed already that I'm anti-reductionist, and I think the current "levels of selection" framework is silly and dated, and has to struggle to explain green-beard genes or altruism. Anyway, that's my 2 cents, as worthless as they may be haha.
