Part I: Tips and techniques from curators Kate Dreher TAIR, AraCyc, PMN Carnegie Institution for Science

Scientists often want to work with more than one gene or protein that are related by a common feature TAIR (and the PMN) offer some basic tools to create customized data sets (e.g. lists of genes or proteins) to add more information to data sets to analyze data sets Sometimes, one gene isnt enough...

Data sets can be based on many different criteria: Overall sequence alignment (DNA or protein) Sequence motifs (DNA or protein) Protein domains and biochemical properties Gene/Protein function Subcellular location Molecular function Biological process Expression pattern Biochemical pathway Mapping region Phenotype Gene families Creating customized data sets using TAIR and the PMN How do you generate these data sets?

Creating customized data sets: TAIR Data sets can be obtained using several strategies at TAIR Advanced search pages Data-mining tools

Creating customized data sets: PMN Data sets can be obtained using several strategies at the PMN What is the PMN? It is the home of AraCyc – the Arabidopsis metabolic pathway database The Plant Metabolic Network (PMN) maintains a set of metabolic pathway databases for Arabidopsis and other plants Provides tools to analyze metabolic data Generates new metabolic pathway databases for crops and other important plants

Pathway Enzyme Gene Reaction Compound Evidence Code AraCyc Pathway pages contain several types of data Metabolic pathway data in AraCyc at the PMN

Pathway pages contain curated comments and useful links Metabolic pathway data in AraCyc at the PMN

You work on a transcription factor that affects jasmonic acid biosynthesis Do JA biosynthetic genes share common sequences in their promoters? Obtain a list of all the genes involved in JA biosynthesis Get upstream promoter sequences Search for over-represented DNA sequences in promoters Creating customized data sets

Customized data sets: JA biosynthesis jasmonic acid

Customized data sets: JA biosynthesis Take this gene list to TAIR... to get upstream sequences

Customized data sets: JA biosynthesis Get upstream promoter sequences

Customized data sets: JA biosynthesis Search for over-represented or prevalent DNA sequences in promoters Use the Motif Analyzer in TAIR to identify common 6-mers AT1G69490 AT1G48270 AT1G11870 AT1G12820

Creating customized data sets You are studying a protein with an exciting new domain: Thr-x-Ala-x-Ile-x-Arg Are there other TxAxIxR proteins? Do they share additional domains? Find all of the proteins that have the TxAxIxR domain Identify all of the other domains found in those proteins

Customized data sets: TxAxIxR proteins Find all of the proteins that have the TxAxIxR domain

Customized data sets: TxAxIxR proteins Identify all of the other domains found in those proteins

Analyzing data sets Sometimes you want to analyze data sets We have a few analysis tools: Analyze = DISPLAY data in a visual manner with a few statistics Data must be pre-cleaned If you want to display quantitative metabolic data on genes, enzymes or compounds OMICS viewer If you want to look for over-represented annotations for a list of genes or proteins All the genes up-regulated in a mutant All of the proteins found in the ovule GO categorization tool

GO categorization Classify your list of genes/proteins using GO annotations

GO categorization

... or use a tool at AmiGO (on hand-out)

Putting TAIR and the PMN to work for you Use TAIR to find detailed information for specific genes or proteins Locus page, gene model page, protein page Many sections, many data types, many external links GBrowse Many tracks New gene confidence scores as part of TAIR9 release Use TAIR and the PMN to generate and work with customized data sets Create and add data to lists of proteins and genes Specific and Advanced Search pages Motif analysis tools FTP files with large data sets Visualize and analyze data OMICs viewer (PMN) GO categorization (TAIR) If youre having trouble getting any information you want...
