A non-specific band detected in the input material at 37 kDa was not immunoprecipitated. ab172730 was used as the isotype control. Western blot was performed on immunoprecipitates of wild-type and HOXA9 knockout HEK-293 cell lysates (ab273706). To generate this image, wild-type and HOXA9 knockout HEK-293 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with VeriBlot for IP Detection Reagent (HRP) (ab131366) for 1 h at room temperature, washed again four times then imaged.

False colour image of Western blot : Anti-HOXA9 antibody [EPR3655(2)] staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab140631 was shown to bind specifically to HOXA9. A band was observed at 35 kDa in wild-type HEK-293 cell lysates with no signal observed at this size in HOXA9 knockout cell line. The HOXA9 band is at approximately 35 kDa. This band is present in the nuclear fraction and is absent in the KO. The identity of the brighter band at 37 kDa is unknown but is non-specific as it is present in all samples. To generate this image, wild-type and HOXA9 knockout HEK-293 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/20000 dilution.

Supplementary information

HOXA9 also known as Homeobox A9 functions as a transcription factor and plays an important role in regulating gene expression during embryonic development and hematopoiesis. The protein has a mass of approximately 27 kDa. It shows expression in hematopoietic progenitor cells as well as in certain tissues like the lungs and the central nervous system. By binding to specific DNA sequences HOXA9 regulates genes that are vital for cellular differentiation and proliferation.
Biological function summary

HOXA9 controls the transition and lineage commitment of hematopoietic stem cells. The protein often interacts as part of a transcriptional complex involving other HOX family proteins to maintain proper gene expression balance. This regulatory function is essential for normal gene expression patterns needed in stem cell differentiation and organ development processes.

Pathways

HOXA9 plays significant roles in the hematopoietic cell lineage and the retinoic acid signaling pathway. Through these pathways it collaborates with other HOX proteins like HOXB4 to maintain stem cell properties and influence the differentiation process. These interactions facilitate the production of necessary blood cell types and ensure effective response mechanisms to various developmental cues.

HOXA9 shows a strong connection with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Overexpression or mutation of HOXA9 disturbs normal hematopoietic processes often leading to these malignancies. The interaction with protein PBX1 also highlights its role in these diseases as their joint involvement frequently appears in leukemogenesis. Understanding how HOXA9 contributes to these pathways is critical for developing targeted therapeutic strategies.

Target data

Sequence-specific transcription factor which is part of a developmental regulatory system that provides cells with specific positional identities on the anterior-posterior axis. Required for induction of SELE/E-selectin and VCAM1 on the endothelial cells surface at sites of inflammation (PubMed : 22269951). Positively regulates EIF4E-mediated mRNA nuclear export and also increases the translation efficiency of ODC mRNA in the cytoplasm by competing with factors which repress EIF4E activity such as PRH (By similarity).
