title: Isolation of virus-like (VL30) elements from the Q10 and D regions of the major histocompatibility complex.
abstract: Previous studies from our laboratory have described two endogenous provirus-like sequences in a series of cosmids spanning the TL region of the major histocompatibility complex (MHC) of normal C57BL/10 mice. At least one of these viruses shares similarities with VL30 elements. To determine if additional VL30-like retroviral elements are integrated in the MHC, we constructed a cosmid library using DNA from a radiation leukemia virus (RadLV)-transformed cell line derived from C57BL/6 mice. The library was first screened using the H-2III (5') probe, which detects Class I genes of the H-2 complex. In the primary screening 163 H-2III positives were isolated. The H-2III-positive isolates were then hybridized with an AKR-derived virus probe, EcoB/S, which contains sequences from both the pol and the env genes of the virus. Nine virus-positive isolates were detected. Localization of these cosmid isolates containing viral sequences within the H-2 complex was done utilizing low-copy probes and confirmed using previously mapped cosmid isolates from other laboratories. We report here the isolation and characterization of VL30-like elements from the Qa and D regions of the MHC of several inbred mouse strains.
