Vanin基因是编码参与辅酶A再循环的泛酰巯基乙胺酶的家族,其催化中间体泛酰巯基乙胺分解为维生素B5以在辅酶A生物合成中再利用。泛酰巯基乙胺酶在这一最基本的细胞过程中的作用在20世纪70年代得到了充分的表征。在接下来的20年里,对泛酰巯基乙胺酶的进一步兴趣很少,直到各种遗传学研究涉及在一系列正常和疾病表型中的vanin基因座,以及随之而来的对泛酰巯基乙胺酶活性的另一种产物半胱胺的兴趣。本报告旨在将早期的生物化学研究与最近的生物学数据结合起来,这些数据表明半胱胺是细胞氧化状态的调节剂。许多研究现在报告了Vanin在炎症,氧化应激,细胞迁移和许多疾病(包括心血管疾病)中的作用。
The Vanin genes are a family that encode pantetheinases involved in recycling Coenzyme A, caytalysing the breakdown of intermediate panetheine to vitamin B5 for reuse in CoA biosynthesis. The role of pantetheinase in this most fundamental of cellular processes, was substantially characterised by the 1970s. The next 20 years saw little further interest in pantetheinase until various genetic studies implicated the vanin locus in a range of normal and disease phenotypes, and a consequent interest in the other product of pantetheinase activity, cysteamine. This report seeks to bring together the early biochemical studies with recent biological data implicating cysteamine as a regulator of the oxidative state of a cell. Numerous studies now report a role for Vanin in inflammation, oxidative stress, cell migration and numerous diseases including cardiovascular disease.
