The human UBE2L3 gene encodes the ubiquitin-conjugating enzyme UbcH7, demonstrated to participate in the ubiquitination of p53, c-Fos, and NF-κBin vitro.We report the fine-mapping of this four-exon gene to chromosome 22q11.2. We have constructed a comprehensive genomic clone contig across this gene, demonstrating that the gene lies adjacent to the microsatellite marker D22S446 and spans approximately 57 kb. Four mRNA species are transcribed from this gene, differing in the length of their 3′ UTR. Sequence comparison of the UBE2L3 cDNA with its murine homologue reveals a remarkably high degree of sequence conservation within the 3′UTR.
