The VP62 genbank entry labels the env gene from nt 5754 to 7691. The 22RV1/CWR-R1 genbank entry is labelled as a "complete proviral genome", and the 'putative' env gene is labelled as nt 5754 to 7691, the same as VP62. (Search the webpage for: "putative envelope polyprotein" to find the env gene label.) But as Mula says, the genbank entry only has limited value, because the evidence for the virus is limited to a gDNA PCR result. (They neither sequenced the viruses, nor isolated the viruses, nor detected any viral RNA.) I'm not sure if further research has been carried out on the 22Rv1/CWR-R1 (assumed) virus since the Paprotka study.
