title: Mouse chromosomal mapping of a murine leukemia virus integration region (Mis-1) first identified in rat thymic leukemia.
abstract: We have previously identified a region of genomic DNA which constitutes the site of frequent provirus integration in rat thymomas induced by Moloney murine leukemia virus (Lemay and Jolicoeur, Proc. Natl. Acad. Sci. USA 81:38-42, 1984). This genetic locus is now designated Mis-1 (Moloney integration site). Cellular sequences homologous to Mis-1 are present in mouse DNA. Using a series of hamster-mouse somatic cell hybrids, we mapped the Mis-1 locus to mouse chromosome 15. Frequent chromosome 15 aberrations have been described in mouse thymomas. Mis-1 represents a putative new oncogene which might be involved in the initiation or maintenance or both of these neoplasms.
