I took the above photo yesterday. As I was processing it, I suddenly froze and thought, "GP 120!"
Check it out:
GP120 is the protein that sits on the outer shell (envelope) of HIV and binds to target cells. A trimer of three gp120 (together with three gp41, another protein) bound together forms the "spike" you see in the above picture.
Something tells me I've been working too hard if I suddenly see gp120 in tulips.
Fascinating, though, how these trimeric structures come up in nature, don't you think?
