Role of a white collar-1-white collar-2 complex in blue-light signal transduction.

The EMBO journal - 15 Sept 1999

Talora C, Franchi L, Linden H, Ballario P, Macino G

Abstract excerpt

Mutations in either white collar-1 (wc-1) or white collar-2 (wc-2) lead to a loss of most blue-light-induced phenomena in Neurospora crassa. Sequence analysis and in vitro experiments show that WC-1 and WC-2 are transcription factors regulating the expression of light-induced genes. The WC proteins form homo- and heterodimers in vitro; this interaction could represent a fundamental step in the control of their...
