To further elucidate the molecular mechanisms of HORMAD1 in tumor cells, we performed HORMAD1 immunoprecipitations followed by nano-HPLC mass spectrometry (MS) to identify endogenous HORMAD1 complexes in two LUAD cell lines, A549 and H1395, which express robust amounts of HORMAD1. The gene discussed is HORMAD1; the disease is neoplasm.
