Cell surface beta-glucosidase involved in cytokinesis, cell wall biogenesis, adhesion to host tissue, and biofilm formation; thus playing an important role in the host-pathogen interaction. Has hydrolytic activity on linear (1->3)-beta-D-glucans such as laminaribiose and other laminarioligosaccharides. Optimum pH is 5.5. Secreted into the medium of cells growing as blastospores as well as those forming hyphae (PubMed:17905924). Secretion is decreased in cells lacking VPS4 (PubMed:19819358). Strongly up-regulated under hypoxic conditions and in white but not opaque cells (PubMed:16854431, PubMed:19798425). Repressed by exposure to caspofungin (PubMed:15917516). Expression is probably regulated by EFG1 since SUN41 has 9 E-boxes in its promoter (PubMed:12492856). Predicted to be a substrate for cleavage by KEX2. Leads to increased cell size, cytokinesis defects, altered sensitivity to the cell wall-modifying substance Congo red, defects in adhesion, and reduced biofilm formation. Belongs to the SUN family.
