The following text describes a protein:
Function:
Polymerizes chitin, a structural polymer of the cell wall and septum, by transferring the sugar moiety of UDP-GlcNAc to the non-reducing end of the growing chitin polymer (Probable). Involved in mating tube and dikaryotic hyphae formation and required for the formation of invading hyphae during plant infection.
Subcellular Localization:
Cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle membrane; Multi-pass membrane protein. Cell tip. Note=A constitutive cytoplasmic pool is present that localizes to intracellular microvesicles termed chitosomes. Chitosomes constitute a separate secretory route distinct from the typical secretory pathway and serve as a vehicle for delivering the enzyme to the sites on the cell surface where polysaccharide sythesis takes place. Localizes to septa of yeast-like cells and to the basal septum separating the living tip cell from the vacuolated part in hyphae. Also localizes to the growing bud tip in yeast-like cells and in a tip-ward gradient at the hyphal apex. Apical localization depends on F-actin and the motor domain, whereas motility requires microtubules.
Domain:
The N-terminal myosin motor-like domain (MMD) supports exocytosis but not long-range delivery of transport vesicles.
