title: Molecularly cloned c-mos(rat) is biologically active.
abstract: A unique rat cellular gene, c-mos(rat), homologous to the transforming sequences, v-mos, of Moloney murine sarcoma virus (M-MSV) was detected by hybridization to a v-mos specific probe. The c-mos(rat) gene was cloned together with its flanking sequences in an 11-kbp EcoRI DNA fragment inserted in vector Charon 4A. Two probes were used to investigate the position and orientation of c-mos(rat) in the clone examined ( D3e ), namely pMSV -31 which contains the sequences specific for the transforming sequences of M-MSV and pCS-1 which harbors 0.5 kbp of 5'-terminal sequences of c-mos(mouse) as well as 0.7 kbp of its flanking sequences. After ligation of a restriction fragment of clone D3e containing c-mos(rat) to a fragment containing the long terminal repeat of M-MSV and transfection of the DNA onto rat cells, we detected foci of transformed cells, thus showing that c-mos(rat) is biologically active. Using DNA framents derived from clone D3e , we studied the conservation of c-mos and of its flanking sequences in several species. c-mos(rat) as well as some of its flanking sequences appeared to be highly conserved in the species studied.
