The Brn-2 transcription factor links activated BRAF to melanoma proliferation.

abstract：:We characterized the organization and expression of PHO5 and PHO3, the tightly linked repressible and constitutive acid phosphatase genes of Saccharomyces cerevisiae. The "constitutive" gene, PHO3, is expressed only when PHO5 is not. Altering PHO5 expression, either through promoter deletions or through mutations in t...
