N-acetylglucosamine-1-phosphate transferase (GlcNAc-1-phosphotrasferase) is a transferase enzyme.
Function
[edit]It is made up of two alpha (
Clinical significance
[edit]It is associated with the following conditions:[1][2]
- mucolipidosis II alpha/beta (I-cell disease) - GNPTAB
- mucolipidosis III alpha/beta (pseudo-Hurler polydystrophy) - GNPTAB
- mucolipidosis III gamma - GNPTG
- stuttering (Kang et al., 2010)
In melanocytic cells, GNPTG gene expression may be regulated by MITF.[3]
