Protein attributes

Sequence length	494 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Involved in the recognition of invading micro-organisms. Binds specifically to beta-1,3-glucan and lipopolysaccharide and induces expression of the antimicrobial peptides drosomycin, cecropin and attacin. Ref.1
Subcellular location	Cell membrane; Lipid-anchor › GPI-anchor. Note: Secreted and attached to the membrane by a GPI-anchor. Ref.1
Developmental stage	Expressed at moderate levels throughout the life cycle. Ref.1
Sequence similarities	Belongs to the insect beta-1,3-glucan binding protein family.
Sequence caution	The sequence AAF33849.1 differs from that shown. Reason: Frameshift at positions 457 and 468.
