ARV1 ARV1 homolog, fatty acid homeostasis modulator [Homo sapiens (human)] - Gene

Summary

Official Full Name: ARV1 homolog, fatty acid homeostasis modulatorprovided by HGNC
Primary source: HGNC:HGNC:29561
See related: Ensembl:ENSG00000173409 MIM:611647; AllianceGenome:HGNC:29561
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: DEE38; EIEE38
Summary: this gene encodes a transmembrane protein that contains a conserved zinc ribbon motif at the N- terminus. A similar protein in mouse is thought to function in fatty acid homeostasis. Mutations in this gene are associated with early infantile epileptic encephalopathy 38. [provided by RefSeq, Nov 2016]
Expression: Ubiquitous expression in testis (RPKM 15.4), thyroid (RPKM 10.7) and 25 other tissues See more

A defect in GPI synthesis as a suggested mechanism for the role of ARV1 in intellectual disability and seizures.

Homozygous splice-variants in human ARV1 cause GPI-anchor synthesis deficiency.
Title: Homozygous splice-variants in human ARV1 cause GPI-anchor synthesis deficiency.
In contrast to wild type human ARV1, neither variant expressed detectable levels of protein in mammalian cells. Mice with a neuronal deletion of Arv1 recapitulated the human phenotype, exhibiting seizures and a severe survival defect in adulthood. Our data support ARV1 deficiency as a cause of autosomal recessive epileptic encephalopathy
Title: Neuronal deficiency of ARV1 causes an autosomal recessive epileptic encephalopathy.
A novel function for Arv1 in regulation of cell division through promotion of the contractile actomyosin ring, which is independent of its lipid transporter activity.
Title: Arv1 promotes cell division by recruiting IQGAP1 and myosin to the cleavage furrow.
Overexpression of human ARV1 could rescue the phenotypes associated with GPI anchor synthesis defect in the yeast arv1Delta mutant. Arv1 function in GPI biosynthesis may be conserved in all eukaryotes, from yeast to humans.
Title: Complementation analysis reveals a potential role of human ARV1 in GPI anchor biosynthesis.
These results implicate ARV1 as a protective factor in lipotoxic diseases due to modulation of fatty acid metabolism.
Title: A functional, genome-wide evaluation of liposensitive yeast identifies the "ARE2 required for viability" (ARV1) gene product as a major component of eukaryotic fatty acid resistance.
Arv1p has a role in sterol movement from the ER and in the ensuing regulation of hepatic cholesterol and bile acid metabolism
Title: Decreased expression of ARV1 results in cholesterol retention in the endoplasmic reticulum and abnormal bile acid metabolism.
ARV1 plays a role in sphingolipid metabolism and complements yeast ARV1

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.
