    Abstract

    Hypoxia, a state of lower than normal tissue oxygen tension, has recently been implicated in a host of human diseases, including cancer, heart disease, and neurological disorders. Novel associations between p97 and other proteins, including UBX-domain-containing proteins (UBX-polypeptides), HIF1 alpha, and a variety of E3 ligases are provided herein. The disclosure provides complexes comprising UBX-domain-containing polypeptides (UBX-polypeptides) and other polypeptides involved in the degradation of ubiquitinated proteins. In addition, the disclosure provides uses for active agents that modulate protein-protein complex formation between an UBX-polypeptide and its complementary-binding substrate. For example, the disclosure provides methods for treating or preventing hypoxia-related disorders or conditions in a patient or a cell by administration of an active agent that modulates the activity of an UBX-polypeptide and/or its complementary binding-substrate. Furthermore, the disclosure provides uses for active agents that modulate HIF1 alpha activity; such agents may be used to modulate processes that are regulated by HIF1 alpha. The disclosure also provides many screening assays to identify test agents that modulate complex formation between an UBX-polypeptide and its complementary-binding substrate or methods for evaluating modes of action and/or effects of active agents that have already been identified as modulators of an UBX-polypeptide and/or its complementary-binding substrate.
