== Function ==
[https://www.uniprot.org/uniprot/ML4_VISAL ML4_VISAL] The A chain is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits by removing adenine from position 4,324 of 28S rRNA. The B chain binds to cell receptors and probably facilitates the entry into the cell of the A chain; B chains are also responsible for cell agglutination (lectin activity). Inhibits growth of the human tumor cell line Molt4.<ref>PMID:15001393</ref> <ref>PMID:1450445</ref> [UniProtKB:P81446]
