What is motif in ChIP-seq?

What is motif in ChIP-seq?

Sequence motifs in DNA and RNA molecules are key players in the regulation of gene expression. Proteins and RNA molecules bind to these motifs in a sequence-specific way to control transcription and subsequent sequestration or degradation of messenger RNA (mRNA).

What is motif in bioinformatics?

In Bioinformatics, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and has been proven or assumed to have a biological significance. The problem is to discover the motifs, i.e. what is the order of letters the particular motif is comprised of.

How do you perform a motif analysis?

There are several ways to perform motif analysis with HOMER….Discovering Motifs de novo (homer2)

1. Parsing input sequences into an Oligo Table.
2. Oligo Autonormalization (optional)
3. Global Search phase.
4. Matrix Optimization.
5. Mask and Repeat.

What is a motif in DNA?

Sequence motifs are short, recurring patterns in DNA that are presumed to have a biological function. Often they indicate sequence-specific binding sites for proteins such as nucleases and transcription factors (TF).

What is de novo motif discovery?

De novo motif discovery allows you to directly query the sequence to discover which motifs are the MOST enriched sequences in your target set. Known motif discovery will simply tell you which of the known motifs is most enriched in your target set.

What is a motif analysis?

Motif Enrichment Analysis (MEA) seeks to determine which DNA-binding transcription factors control the transcription of a set of genes by detecting enrichment of known binding motifs in the genes’ regulatory regions.

What is motif discovery in time series?

Time series motifs are repeated segments in a long time series that, if exist, carry. precise information about the underlying source of the time series. Motif discovery. in time series data has received significant attention in the data mining community.
