CD22 & saporin

CD22 (CD22 Molecule) is a Protein Coding gene. Diseases associated with CD22 include Refractory Hematologic Cancer and Refractory Hairy Cell Leukemia. Among its related pathways are Hematopoietic Stem Cell Differentiation Pathways and Lineage-specific Markers and Innate Immune System. Gene Ontology (GO) annotations related to this gene include carbohydrate binding. An important paralog of this gene is SIGLEC1.

Saporin is a so-called ribosome inactivating protein (RIP), due to its N-glycosidase activity, from the seeds of Saponaria officinalis (common name: soapwort).Saporin depurinate the ribosomal RNA in a specific position; rendering the large subunit of ribosomes unable to bind the elongation factors. The consequent arrest of protein synthesis is responsible for the cytotoxicity.
