Summary: Enables lipoate synthase activity. Acts upstream of or within several processes, including lipoate biosynthetic process; neural tube closure; and response to lipopolysaccharide. Located in mitochondrion. Is expressed in alimentary system; liver; metanephros; salivary gland; and urinary system. Human ortholog(s) of this gene implicated in pyruvate decarboxylase deficiency. Orthologous to human LIAS (lipoic acid synthetase). [provided by Alliance of Genome Resources, Dec 2024]

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.

mRNA and Protein(s)

NM_001310612.1 → NP_001297541.1 lipoyl synthase, mitochondrial isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice site in the 5' region and initiates translation at a downstream start codon compared to variant 1. The encoded isoform (2) has a shorter N-terminus than isoform 1.
