HEATR6 Antibody

What is HEATR6 and why is it significant in research?

HEATR6 (HEAT repeat-containing protein 6) is a protein identified as an amplification-dependent oncogene with particular relevance to cancer research. It supports the formation of multi-protein complexes essential for maintaining cellular structure and function, highlighting its significance in genetic and molecular fidelity . The human HEATR6 protein has high sequence conservation with mouse (93%) and rat (92%) orthologs, suggesting fundamental roles in cellular functions across these species . HEATR6 has been assigned the UniProt ID Q6AI08 and Entrez Gene ID 63897 for the human protein .

The alternative name "Amplified in breast cancer protein 1" (ABC1) suggests HEATR6 may be particularly relevant in breast cancer research. Its apparent involvement in oncogenic pathways makes it a protein of interest for cancer biology studies, particularly those investigating mechanisms of oncogenesis, cellular structure maintenance, and protein complex formation.
