A small region within the DNA-binding domain of GRHL2, aa 425–437, inhibits p300. (A) Schematic of GRHL2 domains. DBD, DNA-binding domain; DD, dimerization domain; TAD, transactivation domain. (B) HAT assays using the indicated GRHL2 fragments, assayed as GST-fusion proteins. (C) GRHL2 aa 425–437 inhibits p300 HAT activity. The indicated fragments derived from GRHL2 were assayed as GST-fusions (left) or recombinant peptides (right) for inhibition of HAT activity. (D) GRHL2 aa 425–437 are required for inhibition of an AP-1 reporter, GAL4 reporter in conjunction with GAL4-p300, MMP1 reporter, or MMP14 reporter. Values represent relative luciferase activity normalized to TK-β-galactosidase control.
