 ## About GO-CAM formats
 + Available formats:
   + [RDF Turtle (TTL)](https://www.w3.org/TR/turtle/){:target="blank"}, a textual syntax for RDF called Turtle that allows an RDF graph to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes.
   + [BlazeGraph Journal (JNL)](https://www.blazegraph.com/){:target="blank"}, The graph store for GO-CAMs using Blazegraph; this data product is currently deprecated. See also the [GO and RDF/SPARQL guide](/docs/sparql)
-  + [Simple Interaction Format (SIF)](http://manual.cytoscape.org/en/stable/Supported_Network_File_Formats.html#sif-format){:target="blank"}, a format convenient for building a graph from a list of interactions.
 
 **Notes**:
 * Individual TTLs (1 TTL for 1 GO-CAM) can also be retrieved from the GitHub repository [noctua-models](https://github.com/geneontology/noctua-models/tree/master/models){:target="blank"}.
-* When using SIFs with [Cytoscape](https://cytoscape.org/){:target="blank"}, we also provide a [gocam-styles.xml](https://s3.amazonaws.com/geneontology-public/gocam/gocam-styles.xml). Read more in the [GO-CAM documentation](/docs/gocam-overview/#visualization-in-cytoscape).
