ab55474 (4μg/ml) staining NBR1 in human skeletal muscle using an automated system (DAKO Autostainer Plus). Using this protocol there is moderate cytoplasmic staining.
Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers 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. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Overlay histogram showing HeLa cells stained with ab55474 (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 (ab55474, 1μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. This antibody gave a positive signal in HeLa cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

NBR1 also known as Neighbor of BRCA1 Gene 1 functions as a receptor for selective autophagy. It recognizes ubiquitinated proteins and delivers them to autophagosomes for degradation. The protein has a molecular weight of approximately 110 kDa. Scientists have observed its expression in a variety of tissues with particularly high levels in the testis and low levels in the lung and kidney.
Biological function summary

NBR1 plays a significant role in the removal of misfolded or damaged proteins through autophagy. It acts within the p62/SQSTM1 complex which links to the autophagic machinery. The complex recruits ubiquitinated substrates facilitating their degradation in lysosomes. Through this mechanism NBR1 helps maintain cellular homeostasis and genome integrity by removing potentially harmful elements.

Pathways

NBR1 integrates into the critical cellular recycling process known as autophagy. It works closely with proteins such as p62/SQSTM1 in the ubiquitin-proteasome pathway to ensure efficient protein turnover. The protein participates in signals that control cell growth and survival influencing the mTOR pathway which is important in regulating cellular metabolism growth and life span.

Research indicates that NBR1 might have implications in neurodegenerative diseases like Alzheimer's and Parkinson's. Its involvement in autophagy suggests that malfunction or aberrant expression of NBR1 could lead to the accumulation of protein aggregates associated with these conditions. Additionally interactions with proteins such as LC3 and p62/SQSTM1 central in lysosomal degradation highlight its potential role in disease mechanisms where autophagy is disrupted.

Target data

Ubiquitin-binding autophagy adapter that participates in different processes including host defense or intracellular homeostasis (PubMed : 24692539, PubMed : 33577621). Possesses a double function during the selective autophagy by acting as a shuttle bringing ubiquitinated proteins to autophagosomes and also by participating in the formation of protein aggregates (PubMed : 24879152, PubMed : 34471133). Plays a role in the regulation of the innate immune response by modulating type I interferon production and targeting ubiquitinated IRF3 for autophagic degradation (PubMed : 35914352). In response to oxidative stress, promotes an increase in SQSTM1 levels, phosphorylation, and body formation by preventing its autophagic degradation (By similarity). In turn, activates the KEAP1-NRF2/NFE2L2 antioxidant pathway (By similarity). Plays also non-autophagy role by mediating the shuttle of IL-12 to late endosome for subsequent secretion (By similarity).
