Woronin sorting complex protein involved in both Woronin bodies (WB) formation and inherence (PubMed:23869404). Localizes to large peroxisome membranes where it self-assembles into detergent-resistant oligomers that envelop hex-1 assemblies, producing asymmetrical nascent WBs (By similarity). These structures are then delivered to the cell cortex, which permits partitioning of the nascent WB and WB inheritance (By similarity). Self-assembles into detergent-resistant oligomers and forms a complex with hexA assemblies. Localizes to nascent and mature Woronin bodies, fungal-specific organelles that plug the septal pore in case of physical damage. Belongs to the peroxisomal membrane protein PXMP2/4 family.
