Annexins and their role in the control of symbioses development in plants

Abstract

Annexins belong to the superfamily of calcium-dependent phospholipid binding proteins. The participation of these proteins in the regulation of structural organization of membranes, vesicular transport and a variety of signal transduction pathways is important for many cellular processes. Despite the structural similarity with animal annexins, plant annexins are characterized by significant variability of the N-terminal region and modification of calcium-binding motifs in II and III repeats, while calcium-binding motifs in I and IV repetitions remain conservative. However, the physiological role of animal and plant annexins, as well as mechanisms of their influence on calcium metabolism, may be similar. This review focused on the latest data about the structure and functioning of plant annexins.
