RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: SPG72; Yip2d; SPG72A; SPG72B; C5orf19; SGC32445
Summary: This gene encodes a member of the receptor expression enhancing protein family. Studies of a related gene in mouse suggest that the encoded protein is found in the cell membrane and enhances the function of sweet taste receptors. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]
Expression: Biased expression in brain (RPKM 30.0), adrenal (RPKM 4.6) and 8 other tissues See more

What's a GeneRIF?

A Nepalese family with an REEP2 mutation: clinical and genetic study.
Title: A Nepalese family with an REEP2 mutation: clinical and genetic study.
Expression of the REEP1/REEP2 subfamily appears to be restricted to neuronal and neuronal-like exocytotic tissues, consistent with neuronally restricted symptoms of REEP1 genetic disorders.
Title: REEP1 and REEP2 proteins are preferentially expressed in neuronal and neuronal-like exocytotic tissues.
We have identified mutations in REEP2 in two families with relatively pure, early-onset hereditary spastic paraplegia, one with autosomal-dominant and the other with autosomal-recessive transmission.
Title: Loss of association of REEP2 with membranes leads to hereditary spastic paraplegia.
In mouse, Reep2 enhances sweet receptor function by a different mechanism than Reep1 uses to enhance olfactory receptor function.
Title: REEP2 enhances sweet receptor function by recruitment to lipid rafts.

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.

NR_073448.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) uses two alternate in-frame splice sites in the coding region, compared to variant 1. This variant is represented as non-coding due to the presence of an upstream ORF that is predicted to interfere with translation of the longest ORF; translation of the upstream ORF renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

Description

Transcript Variant: This variant (4) uses an alternate in-frame splice site in the 5' coding region, compared to variant 1. This variant is represented as non-coding due to the presence of an upstream ORF that is predicted to interfere with translation of the longest ORF; translation of the upstream ORF renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
