Product details:
Human YB1 ELISA Kit (YBX1) (ab269544) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of YB1 (YBX1) protein in cell lysate. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human YB1 (YBX1) with 0.85 ng/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.
Y box binding protein 1 (YB1) or nuclease-sensitive element-binding protein 1 is a DNA- and RNA- binding protein encoded by the *YBX1* gene. YB1 binds preferentially to the 5'-[CU]CUGCG-3' RNA motif and specifically recognizes mRNA transcripts modified by C5-methylcytosine (m5C). YB1 is involved in translational repression, RNA stabilization, mRNA splicing, DNA repair, and transcription regulation.

Y-box Binding Protein 1 (YB1) also known as YBX1 is a multifunctional protein with a mass of approximately 36 kDa. It belongs to the cold shock protein family that contains a highly conserved cold shock domain. YB1 is broadly expressed across many tissues predominantly found in the cytoplasm and nucleus where it functions as a transcription factor and RNA-binding protein. Through its transcriptional regulatory activity YB1 can bind to Y-box sequences in the promoter regions of genes and modulate their expression.
Biological function summary
YB1 plays vital roles in regulating cell proliferation stress response and differentiation. It does not operate alone; it interacts with various complexes notably ribonucleoprotein complexes. YB1 regulates gene expression at both transcriptional and translational levels impacting cell cycle progression and apoptosis pathways. Its ability to bind RNA and DNA makes it integral in controlling the expression of genes related to stress responses and developmental processes.
Pathways
YB1 is essential in many signaling pathways that govern cell growth and survival including the PI3K/AKT pathway and MAPK pathway. In these pathways it interacts with proteins like AKT1 and MAPK3 influencing cellular responses to external and internal stimuli. These interactions reveal the adaptability of YB1 in various cellular contexts allowing it to mediate pathway-specific responses to environmental cues thereby promoting the maintenance of cellular homeostasis and adaptation.
The dysregulation of YB1 has been linked to cancer and neurodegenerative diseases. Overexpression or altered localization of YB1 often in connection with other proteins such as p53 contributes to tumorigenesis by enhancing cell proliferation and inhibiting programmed cell death. In neurodegenerative diseases impaired YB1 function can negatively affect neuronal survival potentially mediated through its interactions with proteins like tau which are implicated in conditions such as Alzheimer's disease. Understanding of these associations highlights the potential of YB1 as a therapeutic target in disease management.
