The function of Ensembl gene identifier ENSG00000100321 (SYNGR1, synaptogyrin 1) is as follows. May play a role in regulated exocytosis. Modulates the localization of synaptophysin/SYP into synaptic-like microvesicles and may therefore play a role in synaptic-like microvesicle formation and/or maturation (By similarity). Involved in the regulation of short- term and long-term synaptic plasticity (By similarity). .
