This gene encodes a protein which is a membrane protein involved in regulating endocytotic complexes. The protein product is described as one of the clathrin-associated sorting proteins, adaptor molecules which ensure specific proteins are internalized. The encoded protein has also been shown to participate in synaptic vesicle recycling through interaction with synaptotagmin 1 required for neurotransmission. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012],

Function:
Domain:The Asn-Pro-Phe (NPF) motifs, which are found in proteins involved in the endocytic pathway, mediate the interaction with the EH domain of SYT1, SYT2, EPS15, EPS15R and ITSN1.,Function:Adapter protein involved in endocytic machinery. May be involved in the vesicle recycling. May facilitate clathrin-coated vesicle uncoating.,similarity:Belongs to the Stoned B family.,similarity:Contains 1 MHD (mu homology) domain.,similarity:Contains 1 SHD (stonin homology) domain.,subcellular location:Some fraction is membrane-associated.,subunit:Interacts with the second C2 domain of synaptotagmins SYT1 and SYT2. Interacts with EPS15, EPS15R and ITSN1. Interacts indirectly with the AP-2 adapter complex.,tissue specificity:Ubiquitous.,
