Product details:
Human Ubiquitin+1 (UBB+1) SimpleStep ELISA® kit (ab303754) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Human Ubiquitin+1 (UBB+1) protein in serum, plasma (hep), plasma (cit), plasma (EDTA) and cell culture media. Quantitate Human Ubiquitin+1 (UBB+1) with 2.472 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
-Single-wash protocol reduces assay time to 90 minutes or less
-High sensitivity, specificity and reproducibility from superior antibodies
-Fully validated in biological samples
-96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (
ab203359
) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Ubiquitin+1 (UBB+1) is an altered form of the ubiquitin protein which plays a significant role in protein degradation. This mutant ubiquitin results from a molecular error during transcription known as a frameshift mutation. The mass of UBB+1 is slightly greater than that of the normal ubiquitin due to an extra amino acid. UBB+1 is expressed primarily in neuronal cells where it accumulates due to its impaired function in tagging proteins for degradation by the proteasome.
Biological function summary
The alteration in UBB+1 affects the cellular protein quality control system. UBB+1 cannot be recognized properly for degradation itself and hinders the ubiquitin-proteasome system (UPS) by competing with normal ubiquitin. UBB+1 does not just influence single proteins; it might also intervene in larger complexes related to proteostasis. Its aberrant accumulation disrupts the clearance of damaged or misfolded proteins which can impact cellular health.
Pathways
Ubiquitin+1 affects several fundamental cellular processes by disturbing the UPS pathway. UBB+1 interacts with proteins involved in the ubiquitin-proteasome pathway such as E1 activating enzymes E2 conjugating enzymes and E3 ligases. Through these associations UBB+1 can induce stress in protein turnover and impair cellular regulation with direct implications in the processes related to protein homeostasis. The effect on these pathways can lead to wider disruptions in cellular signaling and maintenance.
Ubiquitin+1 has a notable impact on neurodegenerative diseases particularly Alzheimer's disease. It is associated with the accumulation of neurofibrillary tangles and plaques seen in these conditions. UBB+1 also connects with proteins like amyloid-beta which play central roles in Alzheimer's pathology. Furthermore UBB+1 accumulation has implications in Huntington’s disease where it links with the aggregation-prone mutant huntingtin protein. These associations highlight the significance of UBB+1 in disease mechanisms involving protein aggregation and cellular stress responses.
