The significance of SH3 domains in functioning of plant cells

Summary

SH3 domains are the important modules of protein-proteins interactions occurring during many cell processes. The functions of SH3 domains are well investigated in animal and yeast cells, while significance of these domains in functioning of plant cells remains practically unclear. Till now only one family has been cloned which includes three SH3-containing proteins from Arabidopsis thaliana engaged in the endocytosis processes. At the same time, study on genome of this plant presumes about ten SH3-proteins and a lot of proteins containing SH3-binding proline-rich sequences. In this review we describe already known processes which occur in the plant cells with participation of SH3-containing proteins. Probable targets of the SH3 domains action and processes the regulation of which is likely an effect of these domains are also considered.
