^aAll sequences presented in the same orientation as the PRE. Partial sites are also listed, with bases that extend past the PRE indicated by dashes.

^bTwo distinct SP1 sites were identified in the wildtype PRE sequence in addition to the GC Box.

^cUnless otherwise indicated, MW are for isoforms listed in the TransFac database [42].

^dMW is calculated from predicted genomic amino acid sequence.

^eOne of several potential GC Box-binding factors.
