CC   -!- FUNCTION: The heterodimer bitisgabonin-1 is a potent inhibitor of the
CC       adhesion of the RGD-dependent integrin alpha-5/beta-1 (ITGA5/ITGB1) to
CC       immobilized fibronectin. {ECO:0000269|PubMed:17203976}.
CC   -!- SUBUNIT: Heterodimer with bitisgabonin (bitisgabonin-1 is the name of
CC       the heterodimer); disulfide-linked. {ECO:0000269|PubMed:17203976}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:17203976}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000269|PubMed:17203976}.
CC   -!- SIMILARITY: Belongs to the disintegrin family. Dimeric disintegrin
CC       subfamily. {ECO:0000305}.
