Chromosome | 2 | NCBI Gene Number | 14043 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables N-acetylglucosaminyl-proteoglycan 4-beta-glucuronosyltransferase activity; glucuronosyl-N-acetylglucosaminyl-proteoglycan 4-alpha-N-acetylglucosaminyltransferase activity; and protein homodimerization activity. Acts upstream of or within with a positive effect on gene expression; protein N-linked glycosylation; and sulfation. Acts upstream of or within several processes, including heparin biosynthetic process; multicellular organismal-level water homeostasis; and skeletal system development. Located in Golgi apparatus and endoplasmic reticulum. Is expressed in several structures, including alimentary system; central nervous system; ear; genitourinary system; and respiratory system. Used to study hereditary multiple exostoses. Orthologous to human EXT2 (exostosin glycosyltransferase 2). PHENOTYPE: Homozygous null embryos lack heparan sulfate, initiate primitive streak formation but fail to form mesoderm, become growth arrested and die around gastrulation. Heterozygotes show various abnormalities in cartilage differentiation; about one-third form one or more exostoses on the ribs. [provided by MGI curators] |
