Function
Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins. Associated with partial T-cell antigen receptor complexes that escape the ER of immature thymocytes, it may function as a signaling complex regulating thymocyte maturation. Additionally it may play a role in receptor-mediated endocytosis at the synapse.

Supplementary info

- Activity summary
Calnexin also known as Canx is a type I integral membrane protein of the endoplasmic reticulum (ER) involved in the process of protein folding. This chaperone protein has an approximate molecular weight of 90 kDa and is known for its role in the quality control of glycoproteins. Calnexin is expressed in the ER of cells where it interacts with nascent polypeptides to ensure proper folding and assembly contributing to cellular homeostasis. It exhibits its function through its lectin-like domain that binds to sugar moieties on glycoproteins.
- Biological function summary
Calnexin facilitates the proper folding of newly synthesized proteins by forming a complex with another chaperone protein called ERp57. This interaction helps in creating the correct disulfide bonds in glycoproteins which is essential for their stability and functionality. The complex often referred to as the calnexin cycle is critical in preventing the aggregation and misfolding of proteins within the ER. This process ensures that only correctly folded proteins proceed to the Golgi apparatus for further processing and transport.
- Pathways
Calnexin plays an important role in the ER-associated degradation (ERAD) pathway and the unfolded protein response (UPR). In these pathways calnexin ensures that misfolded proteins are retained in the ER or targeted for degradation preventing cellular stress. Calnexin is associated with proteins such as calreticulin another chaperone protein with a similar function in the ER. Together they maintain proteostasis within cells and protect against the accumulation of improperly folded proteins.
- Associated diseases and disorders
Calnexin is linked to several conditions including cystic fibrosis and certain neurodegenerative diseases. In cystic fibrosis the misfolding and subsequent degradation of the CFTR protein are associated with calnexin's role in the ERAD pathway. Similarly in neurodegenerative diseases such as Alzheimer's disrupted protein folding and aggregation are linked to ER stress where calnexin and other chaperone proteins like BiP play a pivotal role in managing protein misfolding. Understanding calnexin's role in these disorders can contribute to developing strategies to mitigate faulty protein folding and its pathological consequences.

Immunoprecipitation - Anti-Calnexin antibody - ER Marker (ab22595)
Calnexin was immunoprecipitated using 0.5 mg HeLa (Human epithelial cell line from cervix adenocarcinoma) whole cell extract, 5 μg of Rabbit polyclonal to Calnexin - ER membrane marker and 50 μl of protein G magnetic beads (+).
No antibody was added to the control (-).
The antibody was incubated under agitation with Protein G beads for 10 minutes, HeLa whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10 minutes under agitation.
Proteins were eluted by addition of 40 μl SDS loading buffer and incubated for 10 minutes at 70oC; 10 μl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab22595.

Subcellular distribution of Smn and hnRNP R in isolated mouse embryonic motoneurons.
Lentiviral knockdown of hnRNP R led to a dose-dependent reduction of hnRNP R levels. Calnexin and Smn protein were not altered significantly.
Primary motoneurons or E18 spinal cord tissue, respectively, were lysed with cytosolic and nuclear fractionation buffer, solubilized in Laemmli buffer and boiled for 10 minutes at 99°C. Proteins were then subjected to SDS-PAGE, blotted onto PVDF membrane, incubated with the corresponding antibodies, including ab22595.

Western blot - Anti-Calnexin antibody - ER Marker (ab22595)
Recent batches of ab22595 (AP217379 and AP151845) detect a band of ~ 75 kDa in HeLa, U-2 OS and MCF7 lysates. This band is completely blocked by the immunizing peptide so we believe this represents Calnexin. Moreoever, a band of the same size is detected by other Calnexin antibodies tested.
