What's a GeneRIF?

Lipid-induced antagonism of CrAT might contribute to decreased PDH activity and glucose disposal in the context of obesity and diabetes.
Title: Obesity and lipid stress inhibit carnitine acetyltransferase activity.
this assay can be used to measure carnitine acetyltransferase activity in the same samples, and assays comparing choline O-acetyltransferase and CrAT show that carnitine acetyltransferase is highly active in neuronal tissues and in neuronal cell cultures
Title: Chromatographic separation of reaction products from the choline acetyltransferase and carnitine acetyltransferase assay: differential ChAT and CrAT activity in brain extracts from Alzheimer's disease versus controls.
The predicted full length cDNA sequence of the porcine CRAT gene was characterised and a new 5' variant for dog, rat and mouse was proposed.
Title: The carnitine acetyltransferase gene (CRAT): a characterization of porcine transcripts with insights into the 5'-end variants of mammalian transcripts and their possible sub-cellular localization.
by performing two amino acid replacements a carnitine acetyltransferase can be converted into a pseudo carnitine palmitoyltransferase in terms of substrate specificity
Title: Mutagenesis of specific amino acids converts carnitine acetyltransferase into carnitine palmitoyltransferase.
show for the first time that a single amino acid is able to determine the substrate specificity of carnitine acetyltransferase (CrAT)

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.
