Synonyms AGX; AGX1; AGX2; SPAG2;
Species Homo sapiens
Ensembl Protein ENSP00000271469
InnateDB Gene IDBG-104387 (UAP1)
Protein Structure
UniProt Annotation
Function Converts UDP and GlcNAc-1-P into UDP-GlcNAc, and UDP and GalNAc-1-P into UDP-GalNAc. Isoform AGX1 has 2 to 3 times higher activity towards GalNAc-1-P, while isoform AGX2 has 8 times more activity towards GlcNAc-1-P.
Subcellular Localization Cytoplasm. Note=In spermatozoa, localized to the principal piece of the tail, the neck region of the head and to a lesser extent, the midpiece of the tail.
Disease Associations
Tissue Specificity Widely expressed. Isoform AGX1 is more abundant in testis than isoform AGX2, while isoform AGX2 is more abundant than isoform AGX1 in somatic tissue. Expressed at low level in placenta, muscle and liver.
