Anti-YY1/Ying-Yang 1 Antibody, clone 1M12 ZooMAb^® Rabbit Monoclonal

Transcriptional repressor protein YY1 (UniProt: P25490; also known as Delta transcription factor, INO80 complex subunit S, NF-E1, Yin and yang 1, YY-1) is encoded by the YY1 (also known as INO80S) gene (Gene ID: 7528) in human. YY-1 is a ubiquitously distributed transcription factor of the GLI-Kruppel class of zinc finger proteins. It exhibits positive and negative control on a large number of cellular and viral genes by binding to sites overlapping the transcription start site.  It binds to the consensus sequence 5′-CCGCCATNTT-3′; however, some genes are reported to have a longer binding motif that allows enhanced binding. Its DNA binding domain is localized to amino acids 295-414.  Its effect on transcription regulation is depends on the context in which it binds, and its diverse mechanisms of action include direct activation or repression, indirect activation or repression via cofactor recruitment, or activation or repression by disruption of binding sites or conformational DNA changes. YY-1 activity is regulated by transcription factors and cytoplasmic proteins that have been shown to abolish YY1-mediated activation or repression. It is reported to play an important role in development, differentiation, and DNA repair. It is also shown to act synergistically with the SMAD1 and SMAD4 in bone morphogenetic protein-mediated cardiac-specific gene expression. It binds to SMAD binding elements within the BMP response element of cardiac activating regions. In response to apoptosis signals, it is proteolytically cleaved by caspase-7. However, phosphorylation at serine 118 by casein kinase 2 prevents its cleavage by caspase-7. Mutations in YY1 gene have been linked to insulinoma with marked increase in insulin secretion.  T372R mutation is neomorphic that results in constitutive activation of cAMP and calcium signaling pathways involved in insulin secretion. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1M12 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Transcriptional repressor protein YY1. It targets an epitope within 15 amino acids from the C-terminal half.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
