So am I ;-))
Perhaps we could convince Dave Kristofferson that we should make a
bionet gourp on a slightly broader scope bionet.signaling.
BTW, I am *not* volunteering to spearhead this effort.
The work on mastoparan and related peptides is very interesting, but I
am not sure how it relates to the general phenomenon of activation of
G-proteins by receptors. In general it appears that a number of
non-receptor stimuli can turn these proteins on.
Now that there is an active transducin and a native transducin
structure can anyone see a rational mechanism where by all these data
Also, Nishimoto (here at MGH now) has shown the IGF2R (M6PR) can
activate G-proteins. Is this widely understood and does it make sense?
