  • 功能
    Catalyzes the formation of mannose 6-phosphate (M6P) markers on high mannose type oligosaccharides in the Golgi apparatus. M6P residues are required to bind to the M6P receptors (MPR), which mediate the vesicular transport of lysosomal enzymes to the endosomal/prelysosomal compartment.
  • 组织特异性
    Expressed in the heart, whole brain, placenta, lung, liver, skeletal muscle, kidney and pancreas.
  • 疾病相关
    Defects in GNPTAB are the cause of mucolipidosis type II (MLII) [MIM:252500]; also known as inclusion cell disease or I-cell disease (ICD). MLII is a fatal, autosomal recessive, lysosomal storage disorder characterized by severe clinical and radiologic features, peculiar fibroblast inclusions, and no excessive mucopolysacchariduria. Congenital dislocation of the hip, thoracic deformities, hernia, and hyperplastic gums are evident soon after birth.
    Defects in GNPTAB are the cause of mucolipidosis type III complementation group A (MLIIIA) [MIM:252600]; also known as variant pseudo-Hurler polydystrophy. MLIIIA is an autosomal recessive disease of lysosomal enzyme targeting. Clinically MLIII is characterized by restricted joint mobility, skeletal dysplasia, and short stature. Mildly coarsened facial features and thickening of the skin have been described. Cardiac valvular disease and corneal clouding may also occur. Half of the reported patients show learning disabilities or mental retardation.
  • 序列相似性
    Belongs to the stealth family.
    Contains 1 EF-hand domain.
    Contains 2 LNR (Lin/Notch) repeats.
  • 翻译后修饰
    The alpha- and beta-subunits appear to be generated by a proteolytic cleavage at the Lys-928-Asp-929 bond.
  • 细胞定位
    Golgi apparatus membrane.
