| Abstract: | Myeloproliferative disorders frequently show deletions or rearrangements of the long arm of chromosome 13. We report here the cloning of RNF6, a new gene that maps close to the chromosome 13 breakpoint in a case of myelofibrosis with a t(4;13)(q26;q12). RNF6 is predicted to encode a 685-amino-acid protein with a coiled-coil domain and a RING-H2 finger at the amino and carboxy terminis, respectively. In addition, we have identified a novel motif, Lys-X-X-Leu/Ile-X-X-Leu/Ile (KIL motif), that is located shortly upstream of a subset of RING-H2 proteins, including RNF6. Drosophila g1, rat Neurodap1, and mouse Praja1. FISH and physical mapping indicated that RNF6 is located at 13q12.2 close to marker D13S1121, and it is oriented from telomere to centromere. RNF6 is not disrupted by the t(4;13). |
