False colour image of Western blot : Anti-MPI antibody staining at 1/500 dilution, shown in green; Rabbit Anti-GAPDH antibody [EPR16891] (ab181602) loading control staining at 1/20000 dilution, shown in red. In Western blot, the antibody was shown to bind specifically to MPI. A band was observed at 47 kDa in wild-type HEK-293T cell lysates with no signal observed at this size in MPI knockout cell line ab266298 (knockout cell lysate ab258523). To generate this image, wild-type and MPI knockout HEK-293T cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) at 1/20000 dilution.

Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.

Lysate preparation: Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10). This means that the protein of interest is denatured. If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.

User storage instructions: Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

Supplementary information

Mannose Phosphate Isomerase also known as PMI is an enzyme that catalyzes the interconversion of fructose-6-phosphate and mannose-6-phosphate. This enzyme with a mass of approximately 42 kDa plays an important role in the metabolism of mannose a type of sugar. Expression of Mannose Phosphate Isomerase occurs in many tissues including liver muscle and fibroblasts where it helps maintain the balance of sugar phosphates needed for various cellular functions.
Biological function summary

This enzyme facilitates the processing of mannose through the biosynthesis pathways of glycoproteins and glycolipids. Mannose Phosphate Isomerase is not part of a larger protein complex but it functions independently to execute its role within the cell. It ensures that cells have adequate mannose-6-phosphate which is essential for proper glycosylation a process necessary for protein folding and stability.

Pathways

Mannose Phosphate Isomerase influences the hexosamine biosynthesis pathway and glycolysis. In the hexosamine biosynthesis pathway it works closely with enzymes such as phosphomannomutase to provide critical components for the production of glycosaminoglycans and glycoproteins. In glycolysis it helps integrate mannose into energy production processes by providing intermediates necessary for glucose metabolism.

Defects in Mannose Phosphate Isomerase can lead to conditions such as congenital disorder of glycosylation type Ib and hypoglycemia-related disorders. This enzyme's malfunction disrupts normal glycosylation which is important for protein function and stability linking it to glycosylation disorders. Connections also exist with phosphomannomutase another enzyme affected in similar glycosylation disorders highlighting its relevance in disease pathology.
