| Syntaxin 7 complexes with mouse Vps10p tail interactor 1b , syntaxin 6 , vesicle associated membrane protein ( VAMP ) 8 , and VAMP 7 in b 16 melanoma cells . ^^^ These polypeptides corresponded to Syntaxin 7 , Syntaxin 6 , mouse Vps10p tail interactor 1b ( mVti1b ) , alpha synaptosome associated protein ( SNAP ) , vesicle associated membrane protein ( VAMP ) 8 , VAMP 7 , and the protein phosphatase 1M regulatory subunit . ^^^ Based on these and data reported previously , we propose that Syntaxin 7 / mVti1b / Syntaxin 6 may form discrete SNARE complexes with either VAMP 7 or VAMP 8 to regulate fusion events within the late endosomal pathway and that these events may play a critical role in melanogenesis . . ^^^ |
