Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

textPantothenate kinase 2 (PANK2) catalyzes the reaction of ATP and pantothenate to form ADP and phosphopantothenate. The reaction is inferred to be negatively regulated by CoA, from studies of the mouse enzyme (Zhang et al. 2005). While pantothenate kinase 2 co-purifies with mitocondria, its precise location within the mitochondrion has not been established (Hortnagel et al. 2003; Johnson et al. 2004). Work by Leonardi et al. (2007) supports a model in which the enzyme is located in the intermembrane space, hence freely accessible to small molecules from the cytosol. Deficiencies in PANK2 cause a progressive neurodegenerative disorder associated with iron accumulation in the brain, but the relationship between disease symptoms and pantothenate metabolism remains unclear (Zhou et al. 2001; Zhang et al. 2006).
