FOXC1 transcriptional regulatory activity is impaired by PBX1 in a filamin A-mediated manner.

Abstract excerpt

FOXC1 mutations underlie Axenfeld-Rieger syndrome, an autosomal dominant disorder that is characterized by a spectrum of ocular and nonocular phenotypes and results in an increased susceptibility to glaucoma. Proteins interacting with FOXC1 were identified in human nonpigmented ciliary epithelial cells. Here we demonstrate that FOXC1 interacts with the actin-binding protein filamin A (FLNA). In A7 melanoma cells...
