P 31 (Use 1)

A SNARE protein involved in retrograde Golgi to ER transport

General Information

Distinct sets of SNARE proteins mediate membrane-membrane fusion events between different intracellular compartments. P 31, a Use 1 homolog, is a Qc-SNARE protein and locates to the endoplasmatic reticulum (ER).Together with syntaxin 18, Sec 22b and BNIP 1 it mediates retrograde traffic from the Golgi to the ER.
