Synaptojanin 1

Synaptojanin 1 is a protein that in humans is encoded by the SYNJ1 gene. ^[1]

This gene encodes a phosphoinositide phosphatase that regulates levels of membrane phosphatidylinositol-4,5-bisphosphate. As such, expression of this enzyme may affect synaptic transmission and membrane trafficking. Multiple transcript variants encoding different isoforms have been found for this gene.
