RT   and infect host cells in vitro.";
RL   Eukaryot. Cell 6:1354-1362(2007).
CC   -!- FUNCTION: Spore wall protein involved in the adhesion to host cells
CC       surface glycoaminoglycans (GAGs). Microsporidian spore adherence is an
CC       integral part of activation and host cell infection.
CC       {ECO:0000269|PubMed:17557882}.
CC   -!- SUBCELLULAR LOCATION: Spore wall {ECO:0000269|PubMed:17557882}. Spore,
CC       perispore {ECO:0000269|PubMed:17557882}. Note=Localizes also at the
CC       anchoring disk complex which consists of the polar sac and the
CC       anchoring disk, playing a crucial role in the rupture of the spore wall
CC       and the subsequent release of the polar tube following activation.
CC   -!- DOMAIN: Heparin-binding motifs (HBM) are characterized by an XBBXBX or
CC       XBBBXXBX sequence, where X is any neutral amino acid and B is a
CC       positively charged basic amino acid, and are defined as the consensus
CC       sequence necessary for protein-heparin interactions. HBM motifs may be
CC       involved in spore adherence to host cells.
