Summary: The neuronal excitotoxin quinolinate is an intermediate in the de novo synthesis pathway of NAD from tryptophan, and has been implicated in the pathogenesis of several neurodegenerative disorders. Quinolinate is derived from alpha-amino-beta-carboxy-muconate-epsilon-semialdehyde (ACMS). ACMSD (ACMS decarboxylase; EC 4.1.1.45) can divert ACMS to a benign catabolite and thus prevent the accumulation of quinolinate from ACMS.[supplied by OMIM, Oct 2004]
Expression: Biased expression in kidney (RPKM 17.3), liver (RPKM 10.7) and 1 other tissue See more

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.

NM_001307983.2 → NP_001294912.1 2-amino-3-carboxymuconate-6-semialdehyde decarboxylase isoform 2

See identical proteins and their annotated locations for NP_001294912.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains an alternate exon in its 5' UTR. This variant represents translation initiation at an alternate start codon compared to variant 1; the 5'-most initiation codon, as used in variant 1, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at the alternate start codon to encode an isoform (2) that has a shorter and distinct N-terminus, compared to isoform 1.
