What is gag-fos-fox Fusion Proteins?
-
Transforming proteins coded by fos oncogenes. These proteins have been found in the Finkel-Biskis-Jinkins (FBJ-MSV) and Finkel-Biskis-Reilly (FBR-MSV) murine sarcoma viruses which induce osteogenic sarcomas in mice. The FBJ-MSV v-fos gene encodes a p55 kD protein and the FBR-MSV v-fos gene encodes a p75 kD fusion protein.
