Ribosome Modulation Factors (RMF) were originally described as a set of proteins that appear to be involved in ribosome dimerization activity during the stationary phase of bacterial growth. See this JBchem article. According to this uniprot entry they have also been shown to hinder translation initiation.

Phage Gilgamesh (see phage in PECAAN for all the details) gene 51 (46895-47104) is a 70 aa long protein which aligns by HHPRED to the v (lowercase v not the capital V) chain of crystal 6H4N and to the A chain of crystal 2JRM. Both these chains were annotated as "Ribosome Modulation Factor". Both HHPRED alignments are in the high 80-90% coverage, 99% probability and an e scores of around e-11.

HHpred also aligns to the Pfam entry for ribosome modulation factor, with about the same coverage and e values.

I see no reason to modify the current term used and would stick with "Ribosome Modulation Factor" and it is generic enough to cover how phage might be using these proteins differently than the host but the function is still likely to have something to do with modulating ribosome activity.
