Hi
I just can't see how an iron specific term can be a parent to a copper specific term.
Please consider removing the parent GO:0006879 cellular iron ion homeostasis from
GO:0097578
sequestering of copper ion
GO:0097579
extracellular sequestering of copper ion
GO:0097580
intracellular sequestering of copper ion
unless copper always is sequestered with iron? in which case I think the definition would need some work!
Thanks
Ruth
