CA-1, a novel phosphoprotein, interacts with the promoter of the cab140 gene in Arabidopsis and is undetectable in det1 mutant seedlings.

The Plant cell - 1 Jan 1993

Sun L, Doxsee R A, Harel E, Tobin E M

Abstract excerpt

We have identified and partially purified a DNA binding protein from Arabidopsis that interacts specifically with the phytochrome-responsive promoter of the Arabidopsis cab140 gene. Promoter deletion analyses in transgenic tobacco showed that, if a region that includes the sequence interacting with this protein was deleted, both expression and phytochrome responsiveness were lost. The protein protected a...
