Protein attributes

Sequence length	102 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Subcellular location	Secreted › cell wall Probable. Membrane; Lipid-anchor › GPI-anchor Potential Ref.5 Ref.10.
Induction	Expression decreases in response to ergosterol perturbation or upon entry into stationary phase. Ref.6 Ref.8
Post-translational modification	The GPI-anchor is attached to the protein in the endoplasmic reticulum and serves to target the protein to the cell surface. There, the glucosamine-inositol phospholipid moiety is cleaved off and the GPI-modified mannoprotein is covalently attached via its lipidless GPI glycan remnant to the 1,6-beta-glucan of the outer cell wall layer By similarity.
Disruption phenotype	Increases resistance to lactic acid. Ref.9
Miscellaneous	Present with 1480 molecules/cell in log phase SD medium. Ref.7
Sequence similarities	Belongs to the TOS6 family.
