Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: KUA; CarF; TMEM189
Summary: Co-transcription of this gene and the neighboring downstream gene (ubiquitin-conjugating enzyme E2 variant 1) generates a rare read-through transcript, which encodes a fusion protein comprised of sequence sharing identity with each individual gene product. The protein encoded by this individual gene lacks a UEV1 domain but includes three transmembrane regions. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2009]
Expression: Ubiquitous expression in placenta (RPKM 19.8), esophagus (RPKM 14.6) and 25 other tissues See more

TMEM189 promotes breast cancer through inhibition of autophagy-regulated ferroptosis.
Title: TMEM189 promotes breast cancer through inhibition of autophagy-regulated ferroptosis.
these results assign the TMEM189 gene to plasmanylethanolamine desaturase and suggest that the previously characterized phenotype of Tmem189-deficient mice may be caused by a lack of plasmalogens.
Title: The TMEM189 gene encodes plasmanylethanolamine desaturase which introduces the characteristic vinyl ether double bond into plasmalogens.
TMEM189 could functionally replace CarF in M. xanthus, and knockout of TMEM189 in a human cell line eliminated plasmalogens; study reveals TMEM189 as the long-sought desaturase for animal plasmalogen biosynthesis
Title: A bacterial light response reveals an orphan desaturase for human plasmalogen synthesis.
TMEM189 is a target gene of the BACH1 transcription factor according to ChIP-seq analysis in HEK 293 cells.

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.

RNA

NR_027889.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) includes an additional internal exon, compared to variant 1. This variant is represented as non-coding because the use of the supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
