CC   -!- FUNCTION: A1b binds to basic 7S globulin (BG) and stimulates its
CC       phosphorylation activity. {ECO:0000250}.
CC   -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC       structurally defines this protein as a knottin. {ECO:0000250}.
CC   -!- PTM: The C-terminal glycine may be removed from A1b.
