Summary: Enables pantothenate kinase activity. Involved in coenzyme A biosynthetic process and ergosterol metabolic process. Located in cytoplasm. Used to study pantothenate kinase-associated neurodegeneration. Human ortholog(s) of this gene implicated in cataract and pantothenate kinase-associated neurodegeneration. Orthologous to several human genes including PANK4 (pantothenate kinase 4 (inactive)). [provided by Alliance of Genome Resources, Dec 2024]

Exploring Yeast as a Study Model of Pantothenate Kinase-Associated Neurodegeneration and for the Identification of Therapeutic Compounds.
Title: Exploring Yeast as a Study Model of Pantothenate Kinase-Associated Neurodegeneration and for the Identification of Therapeutic Compounds.
Here, we show that the pantothenate kinase Cab1p, which catalyzes the first step in the metabolism of pantothenic acid for CoA biosynthesis in budding yeast (Saccharomyces cerevisiae), significantly regulates the levels of sterol intermediates and the activities of ergosterol biosynthesis-targeting antifungals.
Title: The yeast pantothenate kinase Cab1 is a master regulator of sterol metabolism and of susceptibility to ergosterol biosynthesis inhibitors.
Complementation studies by bacterial and mammalian genes showed that YDR531W encodes a genuine pantothenate kinase (new gene designation: CAB1, "coenzyme A biosynthesis").

EC 2.7.1.33

Pantothenate kinase, ATP:D-pantothenate 4'-phosphotransferase; cytoplasmic enzyme that catalyzes the first committed step in the universal biosynthetic pathway for coenzyme A (CoA) synthesis; transcription is regulated by Upc2p via a sterol response element; overexpressed human homologs, PANK1 and PANK3, complement yeast hypomorphic alleles, while PANK2, a gene implicated in pantothenate-kinase associated neurodegeneration, partially complements after the mitochondrial transit peptide is removed
