CC   -!- FUNCTION: Trypsin-stable lectin with hemagglutinating activity. Has
CC       mitogenic activity on murine splenocytes. Inhibits HIV-reverse
CC       transcriptase. {ECO:0000269|PubMed:12565897}.
CC   -!- SUBUNIT: Heterodimer of a 29 kDa and a 31 kDa subunit.
CC       {ECO:0000269|PubMed:12565897}.
CC   -!- INDUCTION: Hemagglutinating activity is inhibited by polygalacturonic
CC       acid. {ECO:0000269|PubMed:12565897}.
CC   -!- SIMILARITY: Belongs to the leguminous lectin family. {ECO:0000305}.
