DTX1 deltex E3 ubiquitin ligase 1 [Homo sapiens (human)] - Gene

Summary

Official Symbol: DTX1provided by HGNC
Official Full Name: deltex E3 ubiquitin ligase 1provided by HGNC
Primary source: HGNC:HGNC:3060
See related: Ensembl:ENSG00000135144 MIM:602582; AllianceGenome:HGNC:3060
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: hDx-1; RNF140
Summary: Studies in Drosophila have identified this gene as encoding a positive regulator of the Notch-signaling pathway. The human gene encodes a protein of unknown function; however, it may play a role in basic helix-loop-helix transcription factor activity. [provided by RefSeq, Jul 2008]
Expression: Broad expression in lymph node (RPKM 13.1), spleen (RPKM 9.7) and 18 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
