Galactoside-binding serum lectin of Xenopus laevis. Estrogen-dependent hepatocyte synthesis and relationship to oocyte lectin.

???displayArticle.abstract???
Xenopus laevis serum contains a lectin which binds alpha- and beta-galactosides. It was purified to homogeneity by affinity chromatography and consists of a single subunit with Mr approximately 69,000, associated in a multimer. The lectin is synthesized and secreted by hepatic parenchymal cells, and its synthesis is increased about 2-fold by estrogen treatment, both in vivo and in primary cell cultures. The serum lectin has the same carbohydrate binding properties as an oocyte lectin from X. laevis described previously, is immunologically cross-reactive, and shows similarities in its peptide map. However, marked differences in amino acid composition preclude the possibility that the serum lectin is a precursor of the oocyte lectin.
