The importance of transcription factor HIF in cellular response to hypoxia and various regulatory levels determining its functioning within cells are considered. Special attention is paid to important links of the hypoxia-triggered HIF-mediated mechanism. The review contains retrospective analysis of the search for cellular primary oxygen sensors and their interactions with HIF. It also deals with the interrelation of HIF-mediated and other hypoxia-activated mechanisms and outlines importance of HIF subunits in the cell.
