PDBsumstructure summary

It forms one subunit of the exocyst complex. First discovered in Saccharomyces cerevisiae, this and other exocyst proteins have been observed in several other eukaryotes, including humans.[7] In S. cerevisiae, the exocyst complex is involved in the late stages of exocytosis, and is localised at the tip of the bud, the major site of exocytosis in yeast.[7] It interacts with the Rho3 GTPase.[8] This interaction mediates one of the three known functions of Rho3 in cell polarity: vesicle docking and fusion with the plasma membrane (the other two functions are regulation of actin polarity and transport of exocytic vesicles from the mother cell to the bud).[9] In humans, the functions of this protein and the exocyst complex are less well characterised: this protein is expressed in several tissues and is thought to also be involved in exocytosis.[10]

Interactions edit

EXOC7 has been shown to interact with EXOC4[11][12] and RHOQ.[12]
