Putative GlcNAc-1 phosphotransferase regulatory domain; The Golgi enzyme UDP-GlcNAc-lysosomal enzyme N-acetylglucosamine-1-phosphotransferase (GlcNAc-1-phosphotransferase), an alpha2beta2gamma2 hexamer, mediates the initial step in the addition of the mannose 6-phosphate targeting signal on newly synthesized lysosomal enzymes. GNPTAB encodes the alpha and beta subunits of GlcNAc-1-phosphotransferase, and mutations in this gene cause the lysosomal storage disorders mucolipidosis II and III alpha-beta The alpha-beta subunits contain three identifiable domains separated by so-called spacer regions. This domain is part of the first spacer region, Spacer-1. Studies indicate that GlcNAc-1 lacking spacer-1 exhibits enhanced phosphorylation of several non-lysosomal glycoproteins, while the phosphorylation of lysosomal acid hydrolases is not altered. In view of these effects on the maturation and function of GlcNAc-1, it is suggested to rename 'spacer-1' the 'regulatory-1' domain.

Stealth protein CR3, conserved region 3; Stealth_CR3 is the third of several highly conserved regions on stealth proteins in metazoa and bacteria. There are up to four CR regions on all member proteins. The domain is found in tandem with CR1, CR2 and CR4 on both potential metazoan hosts and pathogenic eubacterial species that are capsular polysaccharide phosphotransferases. The CR domains appear on eukaryotic proteins such as GNPTAB, N-acetylglucosamine-1-phosphotransferase subunits alpha/beta. Horizontal gene-transfer seems to have occurred between host and bacteria of these sequence-regions in order for the bacteria to evade detection by the host innate immune system.

RNA recognition motif 2 (RRM2) found in N-acetylglucosamine-1-phosphotransferase subunits alpha/beta (GNPTAB) and similar proteins; GNPTAB, also termed GlcNAc-1-phosphotransferase subunits alpha/beta, or stealth protein GNPTAB, or UDP-N-acetylglucosamine-1-phosphotransferase subunits alpha/beta, 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. The model corresponds to the RNA recognition motif 2 (RRM2) of GNPTAB. Its functional significance remains to be investigated.
