Data-Driven Prediction and Design of bZIP Coiled-Coil Interactions
Selective dimerization of the basic-region leucine-zipper (bZIP) transcription factors presents a vivid example of how a high degree of interaction specificity can be achieved within a family of structurally similar proteins. The coiled-coil motif that mediates homo- or hetero-dimerization of the bZIP proteins has been intensively studied, and a variety of methods have been proposed to predict ...
متن کاملComprehensive identification of human bZIP interactions with coiled-coil arrays.
In eukaryotes, the combinatorial association of sequence-specific DNA binding proteins is essential for transcription. We have used protein arrays to test 492 pairings of a nearly complete set of coiled-coil strands from human basic-region leucine zipper (bZIP) transcription factors. We find considerable partnering selectivity despite the bZIPs' homologous sequences. The interaction data are of...
متن کاملComparative analysis of coiled-coil prediction methods.
In this study we compare commonly used coiled-coil prediction methods against a database derived from proteins of known structure. We find that the two older programs COILS and PairCoil/MultiCoil are significantly outperformed by two recent developments: Marcoil, a program built on hidden Markov models, and PCOILS, a new COILS version that uses profiles as inputs; and to a lesser extent by a Pa...
متن کاملCoiled-coil interactions mediate serine integrase directionality
Serine integrases are bacteriophage enzymes that carry out site-specific integration and excision of their viral genomes. The integration reaction is highly directional; recombination between the phage attachment site attP and the host attachment site attB to form the hybrid sites attL and attR is essentially irreversible. In a recent model, extended coiled-coil (CC) domains in the integrase su...
متن کاملIdentification of bZIP interaction partners of viral proteins HBZ, MEQ, BZLF1, and K-bZIP using coiled-coil arrays.
Basic-region leucine-zipper transcription factors (bZIPs) contain a segment rich in basic amino acids that can bind DNA, followed by a leucine zipper that can interact with other leucine zippers to form coiled-coil homo- or heterodimers. Several viruses encode proteins containing bZIP domains, including four that encode bZIPs lacking significant homology to any human protein. We investigated th...
