What pLDDT means and how to read it

Function

Catalyzes the hydrolysis of GTP and utilizes this energy to mediate vesicle scission and participates in many forms of endocytosis, such as clathrin-mediated endocytosis or synaptic vesicle endocytosis as well as rapid endocytosis (RE). Associates to the membrane, through lipid binding, and self-assembles into rings and stacks of interconnected rings through oligomerization to form a helical polymer around the vesicle membrane leading to constriction of invaginated coated pits around their necks. Self-assembly of the helical polymer induces membrane tubules narrowing until the polymer reaches a length sufficient to trigger GTP hydrolysis. Depending on the curvature imposed on the tubules,…

Subunit structure

Homodimer; homodimerization is mediated by the dynamin-type G domain which promotes assembly-stimulated GTPase activity. Homo-tetramer formed from two dimers in the absence of lipid. Oligomerizes into a helical polymer that self-assembles around the vesicle membrane, when associated to the membrane through lipid binding. Interacts (via C-terminal proline-rich domain (PRD)) with SNX9 (via SH3…
