How are promoters activated?

How are promoters activated?

A promoter is induced in response to changes in abundance or conformation of regulatory proteins in a cell, which enable activating transcription factors to recruit RNA polymerase.

What are promoters recognized by?

Operons consist of a promoter, which is recognized by the RNA polymerase, an operator, a segment of DNA in which a repressor or activator can bind, and the structural genes that are transcribed together.

What is the purpose of promoter 2.0 prediction server?

Promoter 2.0 Prediction Server. Promoter2.0 predicts transcription start sites of vertebrate PolII promoters in DNA sequences. It has been developed as an evolution of simulated transcription factors that interact with sequences in promoter regions. It builds on principles that are common to neural networks and genetic algorithms.

Which is the best tool for predicting promoters?

PhagePromoter- is a tool for locating promoters in phage genomes, using machine learning methods. This is the first online tool for predicting promoters that uses phage promoter data and the first to identify both host and phage promoters with different motifs. It is part of Galaxy.(Reference: Sampaio M et al. (2019) Bioinformatics.

How is promoter prediction used in vertebrate Polii?

Promoter2.0 predicts transcription start sites of vertebrate PolII promoters in DNA sequences. It has been developed as an evolution of simulated transcription factors that interact with sequences in promoter regions. It builds on principles that are common to neural networks and genetic algorithms.

Is it possible to predict promoter prediction by neural network?

Promoter Prediction by Neural Network (Martin Reese, Lawrence Berkeley Laboratory, CA, U.S.A.) – applicable to eukaryotes and prokarotes (Reference:Reese MG, 2001. Comput Chem 26: 51-56). Dated and prokaryote results must be viewed skeptically.
