ALG1 (ALG1 chitobiosyldiphosphodolichol beta‑mannosyltransferase) is an endoplasmic reticulum‑resident glycosyltransferase encoded by ALG1 gene. This enzyme associates with endoplasmic reticulum membrane and its catalytic domain faces the cytosolic side of the endoplasmic reticulum membrane. ALG1 contains conserved catalytic polypeptide segments that carry residues responsible for sugar‑unit transfer reaction. The enzyme acts upon lipid‑anchored dolichol‑pyrophosphate linked glycan acceptors on the cytosolic face of the endoplasmic reticulum membrane. Polypeptide translation completes at cytoplasmic ribosomes before targeting to endoplasmic reticulum. Enzyme molecule inserts into endoplasmic reticulum membrane with proper topological orientation to place catalytic region on the cytosolic side. ALG1 expression can be detected across most cell types, and its abundance correlates with cellular demand for de novo dolichol‑linked oligosaccharide precursor generation. Correct membrane anchoring and catalytic domain folding are prerequisites for acquiring enzymatic competence.
ALG1 catalyses transfer of mannose sugar unit onto pre‑formed chitobiose‑diphosphodolichol glycan acceptor substrates. This reaction represents one defined early step within dolichol‑linked oligosaccharide biosynthetic cascade. GDP‑mannose serves as the donor substrate on the cytosolic face of the endoplasmic reticulum membrane for this enzymatic reaction. After extension to the Man5GlcNAc2‑PP‑dolichol intermediate, the glycan is flipped to the ER lumen for further elongation. Loss of functional ALG1 interrupts normal elongation of dolichol‑linked glycan precursor. Other glycosyltransferase enzymes inside endoplasmic reticulum cannot fully substitute for this specific mannose‑transfer catalytic activity. Variation in ALG1 functional abundance changes overall cellular capacity to generate complete lipid‑linked glycan precursor molecules. Structural change within catalytic domain may reduce sugar‑transfer turnover rate or modify substrate acceptor preference. Disruption of this early biosynthetic step further influences downstream processing events that rely on fully assembled dolichol‑linked glycan precursors.

The biological functions of ALG1 are focused on dolichol‑linked glycan precursor elongation, mannose moiety catalytic transfer and early N‑glycosylation pathway progression:
Creative Biolabs offers purified ALG1 protein samples via standardized preparation workflows, including full length ALG1 constructs and isolated catalytic domain variants. Isolated catalytic domain fragments may not support complete lipid‑anchored glycan acceptor‑dependent catalytic behaviours, while full length constructs may be suited for early dolichol‑linked glycan biosynthesis‑associated research. All samples receive routine quality screening, and functional relevant observation may only be carried out with full length samples under appropriate simulated molecular environments. All sample batches follow unified processing standards to maintain consistent structural features for comparative laboratory analysis across separate test groups.

Beyond catalog products, Creative Biolabs offers specialized custom services for ALG1 research:
ALG1 may function as endoplasmic reticulum‑resident glycosyltransferase and participate in mannose unit transfer during early dolichol‑linked glycan precursor elongation.
ALG1 functional status may influence early lipid‑linked glycan precursor assembly, serving as a major regulatory mediator of N‑glycosylation‑related biological processes.
No, all ALG1 related products and services are strictly for research use only, not intended for clinical related operations. All material designs and functional tests are only optimized for basic laboratory research scenarios, without matching clinical application standards.
Offerings include full length ALG1 protein, target specific recombinant antibodies and adjustable expression cell research models, supporting dolichol‑linked glycan biosynthesis research.
Laboratory observation schemes may include glycan precursor‑dependent sugar‑transfer related tests to analyse enzyme‑relevant behaviours under simulated molecular environments.
