The authors state:
"In this study,we report that,in the absence of neuronal activity,MeCP2 binds specifically to BDNF promoter III and functions as a negative regulator of BDNF expression.In response to neuronal activity-dependent calcium influx into neurons,MeCP2 becomes phosphorylated and is released from the BDNF promoter,thereby permitting BDNF promoter III-dependent transcription." Reading this statement in isolation,it would be easy to have the impression that MeCP2 works as a negatively acting transcription factor.However,based on the summary of the paper provided above,MeCP2 acts as a _____.
A)gene-specific regulator of chromatin condensation
B)positively acting transcription factor
C)splicing regulator
D)translational regulator

Question

Quizplus · Accepted Answer

MeCP2 acts as a gene-specific regulator of chromatin condensation by binding to the BDNF promoter and repressing its expression in the absence of neuronal activity.
