Data displayed in the MiMI website are drawn from the MiMI database, a repository that integrates data from numerous protein interaction databases and other external biological sources. MiMI also includes text-mined data from NCIBI-based natural language processing of PubMed literature. Much of the data in MiMI comes from curated sources.

Start Your Search - Back to Top

  1. Select the type of search by clicking the navigation tab:

    Use 'Free Text Search' to search by keywords, genes, diseases, or strings of genes.
    Use 'List Search' to search with a list of genes by name or ID.
    Use 'Query Interactions' to search for specific protein interactions.

  2. Enter your genes, gene list, search terms or phrase.

    In Free Text Search, use any phrases or operators permitted by Lucene (See below for example queries). Specify if you want MiMI to search for your terms in only certain fields by adding the field prefix : cellularComponent:nucleus. (For gene lists, click the radio button to specify names or ID, upload a file and copy it if you are using a file).

    For more detailed instructions for using Lucene queries visit: http://lucene.apache.org/java/2_4_0/queryparsersyntax.html

  3. Press submit. The results appear in a summary table.


Navigate Search Results - Back to Top

  1. Scan results and confirm them. Details on merging logic and source databases can be found in the User Manual.

  2. For details on a given gene, click the the gene name.

    To see information about the GO terms describing the gene’s cellular components, biological processes, or molecular functions, click the term link.
    To see all interactors with a gene, click the # under Int
    To see all articles about a gene, click the # under Doc
    To see related pathways, click the # under Path

  3. To open and close any of the information sections, click on the section icon or Show/Hide

  4. To go back and forth in MiMI, use the back and forward buttons in your browser.

  5. To link out to other sources and return, click the desired hyperlink and use the browser’s back button to return to MiMI.

NOTE: Breadcrumbs for navigation are slated for the next version.


View/Analyze Details of the Gene Detail Page - Back to Top

  1. Find basic gene details and gene attributes in the Molecule Details section (open by default)

  2. Examine interactions and literature about interactions by opening the Protein Interactions section

    Get a list of all articles about these interactions by clicking the documents hyperlink. From there, click the See Text link to view the abstract.

    See the article citations on one interaction by clicking the number under the Lit Count column. From there, you can click on the See Text link to see the article abstract.

  3. Examine literature about the selected gene by opening the Literature section.

    Click the page numbers to move through the list.
    Click the PMID to go to the PubMed abstract page.
    Click View under the See Mined Text column to see other genes associated with this gene in the article.
    Click Search Google Scholar to go directly to results from a Google search on the gene.

  4. Examine pathways in which the gene resides by opening the Pathways section.

    Click KEGG ID or Image to see details or a network.
    Click View Related under Genes Related to the Pathways to see a list of all genes related to the pathway.
    From there, click “Show Genes in this pathway that interact” (under theDescription header), to see interacting genes within and outside the pathway.
    NOTE: This may be a large set and take time to load.

  5. Link out to other biological databases such as NCBI Entrez Gene, EMBL-EBI, and others .

  6. Use integrated tools from NCIBI to extend your investigation.

Click Your Purpose Display Presents

Gene2Mesh

Term enrichment and PubMed links. Find overrep-resented MeSH terms for a gene and link out to related articles

MeSH terms that map to the focus gene, ranked by enrichment score. Also displays all genes enriched for a single MeSH term. Enables you to progressively explore a series of genes and MeSH terms and save/download outcomes.

Cytoscape

Network (visual) exploratory analysis and inference. Interactively explore protein-protein interactions

A powerful interactive network showing the focus gene products, its neighbors, and their attributes. You can combine MiMI data with expression data, find shortest paths, recurrent subnetworks, and matches to KEGG pathways.

Netbrowser

Network (visual) exploratory analysis. Quickly view protein interactions and get a list of interactors.

A lightweight interactive network of protein interactions showing the focus gene product and its nearest neighbors. You can get details on proteins, download a list of proteins that interact with the focus gene, and expand one or more nodes (proteins) to see its neighbors.

GIN

Semantic summaries and PubMed links. View text summaries mined from PubMed about the focus gene and its interactors

Summaries extracted from PubMed articles through semantic natural language processing methods. Also displays citation information, and links to networks of interactions.

MiSearch

PubMed queries through an adaptive interface. Search PubMed and quickly refine queries without writing compound SQL statements.

Search results for the focus gene from a PubMed query with a means to quickly refine results through easy-to-formulate compound queries with MeSH terms. Stores selected articles of interest in a Profile and uses them to determine the relevance of results in subsequent searches and order accordingly.

Sample MiMI Queries - Back to Top

If you are interested in any gene that references insulin you can type in: insulin
To find genes with both insulin and receptor in them: insulin AND receptor
Note: The AND (and the OR, below) must be in upper-case letters.
To find genes with the phrase "insulin receptor" surround the word in double quotes: "insulin receptor"
To limit your "insulin receptor" search to homo sapiens, but you are not sure how to spell homo sapiens use the * wildcard: insulin receptor" AND organism:homo*
To find genes that interact in the nucleus you can query by field name: cellularComponent:nucleus
To find genes that interact in the nucleus for either humans or fruit flies, and you cannot remember the spelling of either organism:
cellularComponent:nucleus AND (organism:homo* OR organism:dro*)
Even more fun: to look for genes that interact in the nucleus, for either humans or fruit flys, that specifically reference insulin receptor:
"insulin receptor" AND cellularComponent:nucleus AND (organism:homo* OR organism:dro*
For a gene with a specific Entrez Gene ID, you can use the term geneid, for example search for geneid:1436.

Of course, you can still type in and search on gene names.
