Dynamic flux of membrane between intracellular compartments is a key feature of all eukaryotic cells. Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) play a crucial role in membrane dynamics by facilitating membrane fusion, for example at synapses where small synaptic vesicles (SVs) undergo activity-regulated neuroexocytosis, followed by the endocytic re-cycling of SV proteins and lipids. Recent work shows that the assembly protein 180 (AP180) N-terminal homology (ANTH) domain containing proteins AP180 and clathrin assembly lymphoid myeloid leukaemia (CALM) not only regulate the assembly of the endocytic machinery but also act as sorters for a subset of SNAREs, the vesicle-associated membrane proteins (VAMPs), most notably VAMP/synaptobrevin 2 at synapses. In this review, we summarise the current state of knowledge about the roles of AP180 and CALM family members in clathrin-dependent membrane traffic, the molecular mechanistic basis for their activities and their potential involvement in human disease.
