Description

Y box binding protein 1, commonly referred to as YBX1 or just YB1 by researchers, is a human protein. YBX1 binding has an absolute requirement for the CCAAT box and relative specificity for the Y box. It has a molecular mass of 35,414D and contains 18% basic residues and putative nuclear localization signals. The protein is highly expressed in mouse erythroid myeloid lymphoid clone-1 (EML), a hematopoietic precursor cell line, but is downregulated in myeloid progenitors and in Gmcsf-treated EML cells during myeloid differentiation. YBX1 is expressed at high levels in myeloid leukemic cells at different developmental stages. Knockdown of the protein in a human leukemic cell line inhibited proliferation ability, induced apoptosis, and induced megakaryocytic differentiation in response to arsenic trioxide treatment. YBX1 is downregulated during myeloid differentiation and aberrant expression in leukemic cells may contribute to leukemia development by blocking differentiation.

Application Notes

The stated application concentrations are suggested starting amounts. Titration of the YB1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.

Immunogen

An amino acid sequence from the middle region of human YBX1 (KYAADRNHYRRYPRRR) was used as the immunogen for this YB1 antibody (100% homologous in human, mouse and rat).

Storage

After reconstitution, the YB1 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
