Summary: Enables pantothenate kinase activity. Involved in coenzyme A biosynthetic process. Acts upstream of or within several processes, including aerobic respiration; regulation of mitochondrial membrane potential; and spermatid development. Located in cytosol and mitochondrion. Is active in mitochondrial intermembrane space. Human ortholog(s) of this gene implicated in pantothenate kinase-associated neurodegeneration. Orthologous to human PANK2 (pantothenate kinase 2).

This study showed that PANK2 genes account for disease of patients diagnosed with an Neurodegeneration with brain iron accumulation disorder.
Title: Neurodegeneration with brain iron accumulation.
Pank2(-/-) mice fed with a ketogenic diet developed a pantothenate kinase-associated neurodegeneration-like syndrome
Title: Pantethine treatment is effective in recovering the disease phenotype induced by ketogenic diet in a pantothenate kinase-associated neurodegeneration mouse model.
Data demonstrate that Pank2 localizes to mitochondria. Pank2-defective neurons have an altered mitochondrial membrane potential, a defect further corroborated by swollen mitochondria at the ultra-structural level and by defective respiration.
Title: Pantothenate kinase-associated neurodegeneration: altered mitochondria membrane potential and defective respiration in Pank2 knock-out mouse model.
The data indicate that PanK1 and PanK2 can compensate for each other to supply tissue CoA.
Title: Germline deletion of pantothenate kinases 1 and 2 reveals the key roles for CoA in postnatal metabolism.
expression of PanK2 was higher in human brain compared to mouse brain

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.

RNA

NR_149747.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (6) lacks two alternate internal exons compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
