MLGL, a gJRL was purified from the latex of mulberry by affinity chromatography.
MLGL is a homotetrameric glycoprotein and each subunit has two polypeptide chains.
The heavier and lighter chains have 133 and 21 (or 24) amino acids, respectively.
A pauci-mannose (or complex type) N-glycan is attached to Asn47 in the heavier chain.
MLGL is cytotoxic towards MCF-7 and MDCK cells even at micromolar concentrations.
