text: The first intelectin was discovered in Xenopus laevis oocyte and is named XL35 or XCGL-1. X. laevis oocyte also contains a closely related XCGL-2. In addition, X. laevis embryos secrete Xenopus embryonic epidermal lectin into the environmental water, presumably to bind microbes. XSL-1 and XSL-2 are also expressed in X. laevis serum when stimulated with lipopolysaccharide. Two additional intestinal intelectins are discovered in X. laevis
  Human has two intelectins: hIntL-1 (omentin) and hIntL-2. Mouse also has two intelectins: mIntL-1 and mIntL-2.
