Chromosome | 10 | NCBI Gene Number | 432486 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable UDP-N-acetylglucosamine-lysosomal-enzyme N-acetylglucosaminephosphotransferase activity. Acts upstream of or within carbohydrate phosphorylation; establishment of localization in cell; and secretion of lysosomal enzymes. Predicted to be located in Golgi membrane. Predicted to be active in Golgi apparatus. Used to study mucolipidosis II alpha/beta. Human ortholog(s) of this gene implicated in mucolipidosis II alpha/beta and mucolipidosis III alpha/beta. Orthologous to human GNPTAB (N-acetylglucosamine-1-phosphate transferase subunits alpha and beta). PHENOTYPE: Homozygous mutations cause stunted growth, high lysosomal enzyme levels, skeletal defects, retinal degeneration and secretory cell lesions. Homozygotes for an ENU allele show skeletal and facial defects, altered enzymatic activities, lysosomal storage, Purkinje cell loss, ataxia and premature death. [provided by MGI curators] |
