Major component of Woronin bodies, fungal-specific organelles that occlude septal pores in order to separate intact from damaged compartments (PubMed:23332467, PubMed:23869404). HexA binds directly or indirectly to the Woronin body tether that in turn is anchored at the rim of the septal pore (PubMed:23869404). Woronin bodies are important for stress resistance and virulence (PubMed:23869404). Forms oligomers (By similarity). Self-assembles into hexagonal rods (By similarity). Binds directly or indirectly to the Woronin body tether lah (Probable). Localizes at Woronin bodies, fungal-specific organelles that plug the septal pore in case of physical damage (PubMed:23332467). Binds to the septal pore in a lah-dependent manner (PubMed:23869404). Leads to an increased sensitivity to stressors that affect the integrity of the cell wall and membrane, such as SDS, the antifungal agent fludioxonil, the acyclic sesquiterpene alcohol farnesol and the cell wall perturbing agents Calcofluor White and Congo Red (PubMed:23869404). Does not affect the resistance to hypo-osmotic stress but leads to a higher sensitivity to physical damage (PubMed:23869404). Results in the lack of Woronin bodies (PubMed:23869404). Attenuates virulence in a murine model of infection (PubMed:23869404). Belongs to the eIF-5A family. Hex1 subfamily.
