A sign error

[ozgunbabur]

In the below output, the sentence says that PKCalpha does something by phosphorylating fascin (should be positive-regulation), but the sign is falsely inferred as negative-regulation probably because of the complexity of the sentence.

@danebell: this is a negation detection issue, where "inhibits" is incorrectly modifying "phosphorylating". If it's a syntax issue, not much we can do... BUT, it may be from our semantic negation detection code. Please check.
