Chaperone protein which plays an important role in mitochondrial iron-sulfur cluster (ISC) biogenesis. Interacts with and stabilizes ISC cluster assembly proteins FXN, NFU1, NFS1 and ISCU (PubMed:26702583). Regulates erythropoiesis via stabilization of ISC assembly (PubMed:21123823, PubMed:26702583). May play a role in cell cycle regulation via its interaction with and promotion of degradation of TP53 (PubMed:24625977, PubMed:26634371). May play a role in the control of cell proliferation and cellular aging (By similarity). Molecular adapter that regulates mitochondrial calcium-dependent apoptosis by coupling two calcium channels, ITPR1 and VDAC1, at the mitochondria-associated endoplasmic reticulum (ER) membrane to facilitate calcium transport from the ER lumen to the mitochondria intermembrane space, thus providing calcium for the downstream calcium channel MCU that directly releases it into mitochondria matrix (By similarity).

Grp75 also known as MOT is a chaperone protein with a molecular mass of approximately 75 kDa. This protein is part of the heat shock protein 70 family and often referred to as Grp75 protein or MOT protein. Typically Grp75 is expressed in the mitochondria of eukaryotic cells. Its primary function lies in aiding the folding and assembly of newly synthesized proteins and responding to cellular stress conditions. The MOT-238 and MOT proteins are related variants in this protein family and antibodies like anti-MOT can specifically detect Grp75.
Grp75 facilitates important cellular processes through its involvement in the regulation of mitochondrial homeostasis and cellular stress responses. Grp75 forms complexes with other mitochondrial proteins ensuring proper function of protein import and maintenance of mitochondrial DNA. It plays an essential role in the cellular response to stress by interacting with other heat shock proteins such as Hsp60 and by stabilizing proteins under conditions of thermal and oxidative stress. Additionally Grp75 is connected to the regulation of cell proliferation and apoptosis mechanisms integral to maintaining cellular balance.
Grp75 is heavily involved in the mitochondrial unfolded protein response and apoptosis pathways. It associates with proteins like PINK1 and Parkin which are vital in the selective autophagy of mitochondria known as mitophagy. In response to misfolded proteins Grp75 helps to maintain mitochondrial function and promotes cell survival through interaction with other mitochondrial proteins. The JG1 and 9F8 proteins are also part of these pathways linked through their roles in protein quality control mechanisms within the cell.
Grp75 has been implicated in neurodegenerative diseases such as Parkinson's disease and certain cancers. Mutations or functional deficiencies in Grp75 can disrupt mitochondrial function which is a critical factor in the pathogenesis of Parkinson’s disease. The connection to proteins like PINK1 and Parkin in this context highlights the role Grp75 plays in the etiology of the disorder. In cancer Grp75 contributes to the cellular stress response and its overexpression can lead to drug resistance making it a target of interest for developing therapeutic strategies.

Overlay histogram showing HepG2 cells stained with ab2799 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2799, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (Goat Anti-Mouse IgG H&L (DyLight® 488) preadsorbed ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG3 [MG3-35] (Mouse IgG3, kappa monoclonal [MG3-35] - Isotype Control ab18394, 1µg/1x106 cells) used under the same conditions.

Formalin fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 10 minutes at room temperature and blocked with 1% BSA for 15 minutes at room temperature. Cells were incubated with (left panel) or without (right panel) ab2799 (1:50) for at least 1 hour at room temperature, washed with PBS, and incubated with DyLight 488 goat-anti-mouse IgG secondary antibody (1:400) for 30 minutes at room temperature. F-Actin (red) was stained with Dylight 554 phalloidin, and nuclei (blue) were stained with Hoechst 33342 dye. Images were taken at 20X magnification.
Immunohistochemistry was performed on normal biopsies of deparaffinized human testis tissue. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer and microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:100 with a Mouse Monoclonal Antibody recognizing Grp75/MOT (ab2799) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX.
