 Both of these receptors are trafficked via synaptojanin.Model organisms have been used in the study of Synaptojanin function.A conditional knockout mouse line of synaptojanin 2, called "Synj2tm1a(EUCOMM)Wtsi" was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists — at the Wellcome Trust Sanger Institute.
