CC -!- FUNCTION: Involved with PTP2 and PTP3 in the formation of the polar
CC tube through which the infectious agent is passed on to the host cell.
CC Accounts for at least 70 percent of the mass of the polar tube.
CC -!- SUBUNIT: Interacts with PTP2 and PTP3. {ECO:0000269|PubMed:12076771}.
CC -!- SUBCELLULAR LOCATION: Spore polar tube.
CC -!- DEVELOPMENTAL STAGE: Found in spores. Expression is high during polar
CC tube formation. {ECO:0000269|PubMed:16691553}.
