OHP1: a maize basic domain/leucine zipper protein that interacts with opaque2.

The Plant cell - 1 Feb 1993

Pysh L D, Aukerman M J, Schmidt R J

Abstract excerpt

OPAQUE2 (O2) is a regulatory gene that predominantly affects the expression of the 22-kD class of zein storage protein genes at the level of transcription. The O2 gene encodes a polypeptide belonging to the basic domain/leucine zipper (bZIP) class of transcriptional regulatory proteins. Our prior analyses have demonstrated that the O2 protein binds 22-kD zein gene promoters as a homodimer in vitro and have also...
