-'''Intersectin''' (ITSN) is an endocytic multidomain scaffold protein in neurons and is important regulator of synaptic vescicles replenishment at hippocampal synapses.  The replenishment is needed in order to sustain neurotransmission during periods of elevated activity. ITSN interacts with synapsin I through its SH3 domains<ref>PMID:29229830</ref>. Alternative splicing of ITSN generates a short isoform with 2 EH (Eps15 homology) domains and 5 SH3 domains and a long isoform with additional DH, PH and C2 domains<ref>PMID:19037327</ref>,<ref>PMID:10922467</ref>.

 '''ITSN 2''' is also involved in clathrin-mediated endocytosis and is very similar to '''ITSN 1'''.
