PANK2 Peptide - Middle Region Blocking Peptide

This gene encodes a protein belonging to the pantothenate kinase family and is the only member of that family to be expressed in mitochondria. Pantothenate kinase is a key regulatory enzyme in the biosynthesis of coenzyme A (CoA) in bacteria and mammalian cells. It catalyzes the first committed step in the universal biosynthetic pathway leading to CoA and is itself subject to regulation through feedback inhibition by acyl CoA species. Mutations in this gene are associated with HARP syndrome and pantothenate kinase-associated neurodegeneration (PKAN), formerly Hallervorden-Spatz syndrome. Alternative splicing, involving the use of alternate first exons, results in multiple transcripts encoding different isoforms. [provided by RefSeq, Jul 2008]

PANK2: a pantothenate kinase that catalyzes the first committed step in the biosynthesis of coenzyme A, an essential cofactor in cellular metabolism. PANK2 is predominantly localized in mitochondria in primates. Defects in PANK2 are the cause of pantothenate kinase-associated neurodegeneration (PKAN), an autosomal recessive neurodegenerative disorder associated with iron accumulation in the brain. Three isoforms of the human PANK2, produced by alternative splicing, have been reported.
