Analysis of interactions between heterologously produced bHLH and MYB proteins that regulate anthocyanin biosynthesis: quantitative interaction kinetics by Microscale Thermophoresis.

Abstract excerpt

The two Arabidopsis basic-helix-loop-helix transcription factors GLABRA3 (GL3) and ENHANCER OF GLABRA3 (EGL3) are positive regulators of anthocyanin biosynthesis, and form protein complexes (MBW complexes) with various R2R3 MYB transcription factors and a WD40 repeat protein TRANSPARENT TESTA GLABROUS1 (TTG1). In earlier studies, GL3, in contrast to EGL3, was shown to be essential for accumulation of anthocyanins...
