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.

Glucosidase 2 subunit beta also known as PRKCSH plays an important role in protein processing within the endoplasmic reticulum (ER). This protein forms part of the heterodimeric enzyme complex glucosidase II responsible for cleaving glucose molecules during glycoprotein maturation. With a molecular weight of about 60 kDa glucosidase 2 subunit beta is important for efficient N-linked glycosylation which is a fundamental process for protein folding and quality control. This protein localizes mainly to the ER where it contributes to proper cellular functions by aiding in the preparation of proteins for trafficking to their final destinations.
Glucosidase 2 subunit beta is associated with protein maturation and quality control within the ER lumen. It is part of the glucosidase II complex which functions to trim glucose residues from N-linked oligosaccharides on nascent glycoproteins facilitating their proper folding and preventing misfolded proteins' accumulation. This activity ensures that only properly folded proteins progress through the secretory pathway while faulty proteins are targeted for degradation. Through these processes glucosidase 2 subunit beta supports cellular homeostasis and protein turnover.
Glucosidase 2 subunit beta plays an influential role in the protein processing and ER-associated degradation (ERAD) pathways. The protein operates within these pathways to regulate glycoprotein folding impacting the unfolding protein response (UPR). It interacts with several proteins including calnexin and calreticulin which are key players in the glycoprotein folding process. Moreover the proper function of glucosidase 2 subunit beta in these pathways is necessary for maintaining the cellular stress response ultimately ensuring efficient cell function and survival.
Defects in glucosidase 2 subunit beta have links to autosomal dominant polycystic liver disease (PCLD). Mutations in PRKCSH which encodes glucosidase 2 subunit beta can lead to the development of PCLD due to disrupted glycoprotein folding and ER stress-induced apoptosis. Additionally abnormalities in its function may indirectly connect to diabetes mellitus by affecting insulin receptor glycosylation and secretion processes. These relationships illustrate the broader impact of glucosidase 2 subunit beta on health and disease providing insight into potential therapeutic targets for treatment strategies.
