Predicted GPI-ancored adhesin-like protein which may be involved in filamentous growth and chlamydospore formation. Accumulates in the bud of yeast cells and in the distal end of the germ tube and hyphal tip cell. Induced during chlamydospore formation and filamentous growth. Expression is regulated by the NRG1 and TUP1 transcription factors. The PGA55 mRNA is transported by SHE3 to bud in yeast cells, as well as to the hyphal tips during filamentous growth.
