In-depth analysis of protein-protein interaction specificities of the MYB protein family of Arabidopsis thaliana revealed a conserved amino acid signature ([DE]Lx(2)[RK]x(3)Lx(6)Lx(3)R) as the structural basis for interaction between MYB and R/B-like BHLH proteins. The motif has successfully been used to predict new MYB/BHLH interactions for A. thaliana(More)
Basic helix-loop-helix (bHLH) transcription factors (TFs) belong to a family of transcriptional regulators present in three eukaryotic kingdoms. Many different functions have been identified for these proteins in animals, including the control of cell proliferation and development of specific cell lineages. Their mechanism for controlling gene transcription(More)
Genetic analyses have demonstrated that together with TTG1, a WD-repeat (WDR) protein, TT2 (MYB), and TT8 (bHLH) are necessary for the correct expression of BANYULS (BAN). This gene codes for the core enzyme of proanthocyanidin biosynthesis in Arabidopsis thaliana seed coat. The interplays of TT2, TT8, and their closest MYB/bHLH relatives, with TTG1 and the(More)
Basic helix-loop-helix (bHLH) transcription factors represent a family of proteins that contain a bHLH domain, a motif involved in binding DNA. Recently, two groups independently analyzed the BHLH gene family of Arabidopsis thaliana (Heim et al., 2003; Toledo-Ortiz et al., 2003). These analyses revealed that this family is one of the largest transcription(More)
Adverse reproductive outcomes were sought via medical records of 14 central Arkansas hospitals serving a five county area encompassing 28, 102 live births in the 1980 to 1982 study period. This population-based study estimated the overall congenital anomaly case incidence to be 3.5 percent of live births. Information on pregnancy history of the cases or on(More)
