Synaptobrevin homolog YKT6 is a protein that in humans is encoded by the YKT6 gene.^[1][2][3]

Function

This gene product is one of the SNARE recognition molecules implicated in vesicular transport between secretory compartments. It is a membrane associated, isoprenylated protein that functions at the endoplasmic reticulum-Golgi transport step. This protein is highly conserved from yeast to human and can functionally complement the loss of the yeast homolog in the yeast secretory pathway.^[3]

Interactions

YKT6 has been shown to interact with BET1L.^[4][5]
