per·me·ase

(per'mē-ās),
Any of a group of membrane-bound carriers (enzymes) that effect the transport of solute through a semipermeable membrane; this term is not typically used to describe eukaryotes.

n.
Any of several cell-membrane proteins that function as channels for the passive transport of a specific molecule in or out of the cell.
