Family Report for: Maspardin-ACP33-SPG21_like


Block X
Parent Family : Abhydrolase_6


ACP33 binds the intracellular domain of CD4. Mutation S109A abolishes the interraction. S109 is in similar position as active site serine of a/b hydrolase. Maspardin-ACP33-SPG21 gene is mutated in Mast Syndrome (Cross and McKusick 1967, Simpson et al 2003), a Complicated Form of hereditary spastic paraplegia associated with dementia. Ishiura et al. (2014) reported 2 Japanese brothers with autosomal recessive SPG21. The patients had onset of gait disturbances in their fifties and sixties, much later than that reported by Cross and McKusick (1967). Maspardin is conserved in metazoans but independent losses of this gene occured in two relatively distant ecdysozoan taxa: dipterans and nematodes (Chertemps etal.). Extracellular vesicles from Echinococcus granulosus (Platyhelminthe-Cestode) larval stage contain an orthologue of maspardin (Nicolao 2019). A Novel alpha/beta-hydrolase gene IbMa, homologous to maspardin, enhances salt tolerance in transgenic Sweetpotato (Liu et al. 2014) OsMas1 in rice (Wang et al. 2022)
