A new variant of B1 elements, vB1, identified upstream of a retroviral integration site.
A new variant of the murine B1 retroposon family, vB1, was identified in antisense orientation 165 bases upstream of the integration site of RFB MuLV in infected NIH3T3 fibroblasts. vB1 revealed a characteristic B1 structure, but contained two additional unique repeats. This variant facilitates identification of related vB1 elements which are considered to represent a minor subgroup of B1 elements.
