frp1- reduces ferric ion to ferrous
fip1/fio1 - complex (?) transports ferrous ion into cell
fep1 - represses the above genes when iron is available
to do:
fep1 represses "during cell response to iron" NOT "during cell response to iron starvation"
fip1 should have ferrous ion import? (fio1 does)
complex annotation fip and fio?
