The N-terminal domain (also called FERM domain) binds sodium-hydrogen exchanger regulatory factor (NHERF) protein (involving long-range allostery).[7] This binding can happen only when ezrin is in its active state. The activation of ezrin occurs in synergism of the two factors: 1) binding of the N-terminal domain to phosphatidylinositol(4,5)bis-phosphate (PIP2) and 2) phosphorylation of threonine T567 in the C-terminal domain.[8][9] Binding to actin filaments (via C-terminal) and to membrane proteins (via N-terminal) stabilizes the protein's conformation in its active mode. The membrane proteins like CD44 and ICAM-2 are indirect binding partners of ezrin, while EBP50 (ERM binding protein 50) can associate with ezrin directly.[10]

One thought on “Cannabaceae”
Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
