I have always been using those commands in R for getting my protein network to be visualized in the string-db site.
However now only the first protein of the list get visualized.

By putting this link on the browser "string-db.org/10/p/9425227685" I get redirected to this page:
that is telling me that 261 proteins are detected in Mus musculus, 1 in Drosophila melanogaster, 1 in Lawsonia intracellularis, and 1 in Danaus plexippus. When I select "Mus musculus" and click on "continue", the first protein get recognized but all the others not:
Arfgef2 - ADP-ribosylation factor guanine nucleotide-exchange factor 2 (brefeldin A-inhibited); Promotes guanine-nucleotide exchange on ARF1 and ARF3 and to a lower extend on ARF5 and ARF6. Promotes the activation of ARF1/ARF5/ARF6 through replacement of GDP with GTP. Involved in the regulation of Golgi vesicular transport. Required for the integrity of the endosomal compartment. Involved in trafficking from the trans-Golgi network (TGN) to endosomes and is required for membrane association of the AP-1 complex and GGA1. Seems to be involved in recycling of the transferrin receptor from recycling [...]
- - Sorry, STRING found no proteins by this name in Mus musculus - -
I guess it is for this "0D" suffix which is added before the protein identifier. I do not know why this happens because on my R "mapped" object there is not:
