Function

Protein with pleiotropic attributes mediated in a cell-compartment- and tissue-specific manner, which include the plasma membrane-associated cell signaling functions, mitochondrial chaperone, and transcriptional co-regulator of transcription factors in the nucleus (PubMed:11302691, PubMed:20959514, PubMed:28017329, PubMed:31522117). Plays a role in adipose tissue and glucose homeostasis in a sex-specific manner (By similarity). Contributes to pulmonary vascular remodeling by accelerating proliferation of pulmonary arterial smooth muscle cells (By similarity). In the mitochondria, together with PHB2, forms large ring complexes (prohibitin complexes) in the inner mitochondrial membrane (IMM) and functions as a chaperone protein that stabilizes mitochondrial respiratory enzymes and maintains mitochondrial integrity in the IMM, which is required for mitochondrial morphogenesis, neuronal survival, and normal lifespan (Probable). The prohibitin complex, with DNAJC19, regulates cardiolipin remodeling and the protein turnover of OMA1 in a cardiolipin-binding manner (By similarity). Regulates mitochondrial respiration activity playing a role in cellular aging (PubMed:11302691). The prohibitin complex plays a role of mitophagy receptor involved in targeting mitochondria for autophagic degradation (PubMed:28017329). Involved in mitochondrial-mediated antiviral innate immunity, activates RIG-I-mediated signal transduction and production of IFNB1 and pro-inflammatory cytokine IL6 (PubMed:31522117). In the nucleus, acts as a transcription coregulator, enhances promoter binding by TP53, a transcription factor it activates, but reduces the promoter binding by E2F1, a transcription factor it represses (PubMed:14500729). Interacts with STAT3 to affect IL17 secretion in T-helper Th17 cells (PubMed:31899195). In the plasma membrane, cooperates with CD86 to mediate CD86-signaling in B lymphocytes that regulates the level of IgG1 produced through the activation of distal signaling intermediates (By similarity). Upon CD40 engagement, required to activate NF-kappa-B signaling pathway via phospholipase C and protein kinase C activation (By similarity).

Activity summary

Prohibitin often known as PHB is a 30 kDa protein that plays significant mechanical roles in cellular processes. It is widely present in various tissues and cells acting as a mitochondrial marker and associates with other mitochondrial markers. Prohibitin protein exists in a highly conserved structure which makes it essential across different species. It localizes within the inner mitochondrial membrane where it exerts functions important for cellular energy homeostasis and mitochondrial stability.

Biological function summary

The protein is involved in the regulation of mitochondrial respiratory function and stabilization of mitochondrial nucleoid. Prohibitin protein forms a complex with related proteins contributing to the maintenance of mitochondrial morphology and integrity. Its role extends to cell cycle control and apoptosis making it a significant player in cellular proliferation and survival. Additionally it influences cellular senescence and stress responses offering protection against various stressors.

Pathways

Prohibitin integrates into mitochondrial dynamics and energy production pathways. It participates in the regulation of oxidative phosphorylation a core component for ATP generation. Prohibitin collaborates with proteins like co-chaperones and complexes such as the inner mitochondrial membrane complex which further illustrates its integration into cellular pathways. The interplay of these proteins and pathways underlines Prohibitin's role in maintaining mitochondrial function.

Associated diseases and disorders

Prohibitin shows notable connections to cancer and neurodegenerative diseases. Its dysregulation links to the progression of cancers where it interacts with the retinoblastoma protein influencing cellular proliferation pathways. In neurodegenerative diseases Prohibitin participates in mechanisms that may affect the development of conditions like Alzheimer's disease associated with its role in mitochondrial dysfunction and oxidative stress. These interactions highlight Prohibitin's importance in both health and disease contexts and its potential as a therapeutic target.

    Overlay histogram showing HeLa cells stained with ab210424 (red line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilized with 90% methanol for 30 min at -20°C. The cells were then incubated in 1x PBS / 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (ab210424, 1/500 dilution) for 30 min at 22°C.

    Isotype control antibody (black line) was rabbit IgG (monoclonal) Phycoerythrin (PE Rabbit IgG, monoclonal [EPR25A] - Isotype Control ab209478) used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

    Acquisition of >5,000 events were collected using a 50mW Yellow-Green laser (561nm) and 586/15 bandpass filter.

The cells were fixed with 4% formaldehyde (10 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab210424 at 1/100 dilution (Pseudocolored in green) and Alexa Fluor® 647 Anti-Tubulin antibody [YOL1/34] - Microtubule Marker ab195884, Rat monoclonal to Tubulin (Alexa Fluor® 647), at 1/250 dilution (shown in red). Nuclear DNA was labelled with DAPI (shown in blue).

    Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
