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: hTE; NAP1; PTE1; PTE2; PTE-1; PTE-2; HNAACTE; hACTE-III
Summary: The protein encoded by this gene is a peroxisomal thioesterase that appears to be involved more in the oxidation of fatty acids rather than in their formation. The encoded protein can bind to the human immunodeficiency virus-1 protein Nef, and mediate Nef-induced down-regulation of CD4 in T-cells. [provided by RefSeq, Oct 2010]

Protein interactions

Protein	Gene	Interaction	Pubs
Nef	nef	HIV-1 Nef (from strains NA7 and NL4-3 only) directly interacts with ACOT8 in 293T cells and this interaction is mediated by residues in the Nef core domain as shown by FACS-Forster resonance energy transfer (FRET)-based methods	PubMed
	nef	HIV-1 Nef is identified to have a physical interaction with acyl-CoA thioesterase 8 (ACOT8) in human HEK293 and/or Jurkat cell lines by using affinity tagging and purification mass spectrometry analyses	PubMed
	nef	Point mutations in HIV-1 Nef at amino acids Asp108, Leu121, Pro122, and Asp123 abrogate the ability of Nef to bind hTE , downregulate CD4 and MHC class I, and dimerize, indicating a key role for this region of Nef in mediating most of its known functions	PubMed
	nef	Amino acids 108-152 mediate binding of HIV-1 Nef to the human Thioesterase II protein (hTE/ACOT8), an interaction that enhances hTE enzymatic activity	PubMed

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.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

NM_183385.1: Suppressed sequence

Description

NM_183385.1: This RefSeq was temporary suppressed because insufficient evidence exists for the exon combination of this transcript variant, and because it is nonsense-mediated decay (NMD) candidate.
NM_183386.1: Suppressed sequence

Description

NM_183386.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
