[transport] defs needed

[Jennifer Deegan (nee Clark)]

Hi,

Does anybody know how these terms should be defined? They're all outside 
the experience of the transport working group members.

dihydropyridine-sensitive calcium channel activity GO:0015270
(used by human and mouse)

store-operated calcium channel activity GO:0015279
(human/rat/worm/fly/mouse)

volume sensitive anion channel GO:0005225
(used by Drosopila)

excitatory extracellular ligand-gated ion channel activity GO:0005231
Note:  Although there is only one direct annotation (Drosophila ISS) 
this term has children used for many annotations (mouse/rat/zfish/worm) 
which DO NOT appear to specify 'excitatory' ....should they?

amiloride-sensitive sodium channel activity GO:0015280<br>
(used by mouse/rat/zebrafish/fly/human)

Thanks,

Jen
