Identification of an M-CAT-positive regulation site. A,
diagram of serial shortening of the positive region I in the D1L promoter and
the M-CAT deletion construct (ΔM-CAT). B, relative
promoter activity of these deletion construct mutants in EOMA cells
(n = 6, *, denotes p < 0.001). C,
activity of the M-CAT reporter construct in EOMA cells (n = 6,
*, denotes p < 0.001). The data are representative of
three independent experiments.
