Table 1.

Overexpression of Munc18-2, open-syntaxin, and SNAP-25 do not affect the transcription level of unrelated proteins but overexpression of Munc18-2 increased the transcription of syntaxin

SNAP-250.81.1>50000.80.90.6
  • The results are expressed as fold increase over endogenous expression level. We detected mRNA of Munc18-1 and -2 but they were pooled together since both isoforms share most features.
