Target Background

May play a role as a negative regulatory factor in CD4-dependent T-cell activation.
Gene References into Functions
  1. HBV X gene enhanced SPG21 gene promoter activity, SPG21 mRNA expression and SPG21 protein production in HepG2 cells in a dose-dependent manner. PMID: 21205478
  2. frameshift results in the premature termination of the encoded product, which is designated "maspardin" (Mast syndrome, spastic paraplegia, autosomal recessive with dementia) PMID: 14564668
  3. Data report that maspardin localizes prominently to cytoplasm as well as to membranes, possibly at trans-Golgi network/late endosomal compartments, and that maspardin interacts with the aldehyde dehydrogenase ALDH16A1. PMID: 19184135
Involvement in disease
Spastic paraplegia 21, autosomal recessive (SPG21)
Subcellular Location
Cytoplasm, cytosol. Membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Golgi apparatus, trans-Golgi network membrane; Peripheral membrane protein. Note=Partially localized in the cytosol but also accumulated on an intracellular vesicular compartment. Colocalizes with CD4 on endosomal/trans-Golgi network.
Protein Families
AB hydrolase superfamily
Tissue Specificity
Expressed in all tissues tested, including heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Expressed in J.CaM1.6, HuT 78 and HeLa cell lines (at protein level).
