Structure, function and membrane interactions of plant annexins: an update.
Knowledge accumulated over the past 15 years on plant annexins clearly indicates that this disparate group of proteins builds on the common annexin function of membrane association, but possesses divergent molecular mechanisms. Functionally, the current literature agrees on a key role of plant annexins in stress response processes such as wound healing and drought tolerance. This is contrasted ...
متن کاملAnnexins: from structure to function.
Annexins are Ca2+ and phospholipid binding proteins forming an evolutionary conserved multigene family with members of the family being expressed throughout animal and plant kingdoms. Structurally, annexins are characterized by a highly alpha-helical and tightly packed protein core domain considered to represent a Ca2+-regulated membrane binding module. Many of the annexin cores have been cryst...
متن کاملAnnexins as Overlooked Regulators of Membrane Trafficking in Plant Cells
Annexins are an evolutionary conserved superfamily of proteins able to bind membrane phospholipids in a calcium-dependent manner. Their physiological roles are still being intensively examined and it seems that, despite their general structural similarity, individual proteins are specialized toward specific functions. However, due to their general ability to coordinate membranes in a calcium-se...

olipin and is responsible for increased catalysis, whereas direct interaction between CT V< 5 and acidic PLA 2 inhibits enzyme activity. It is concluded tha t variabilít} in substrate composition and the chemical nature of both PLA 2 and cationic peptide determine whether enzyme activity is affected by substrate packing or by direct enzyme-peptide interaction. Models of interactions of PLA 2 wi...
متن کاملAnnexins in Cell Membrane Dynamics
The sarcolemma of smooth muscle cells is composed of alternating stiff actin-binding, and flexible caveolar domains. In addition to these stable macrodomains, the plasma membrane contains dynamic glycosphingolipid- and cholesterol-enriched microdomains, which act as sorting posts for specific proteins and are involved in membrane trafficking and signal transduction. We demonstrate that these li...
