CC -!- FUNCTION: Galactose and N-acetyllactosamine specific lectin. Binds to
CC the H-2 blood type determinant fucosyl-N-acetyllactosamine.
CC -!- SUBUNIT: Homodimer.
CC -!- PTM: A minor C-terminal proteolytic processing site is observed at
CC position 268. {ECO:0000269|PubMed:7852319}.
CC -!- MISCELLANEOUS: Binds one manganese (or another transition metal) ion
CC and one calcium ion.
CC -!- SIMILARITY: Belongs to the leguminous lectin family. {ECO:0000305}.
