| Addtional Information | FUNCTION: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 (By similarity). Less toxic than abrin-a.FUNCTION:The B chain is a galactose-specific lectin that facilitates the binding to the cell membrane that precedes endocytosis (By similarity).CATALYTIC ACTIVITY:Endohydrolysis of the N-glycosidic bond at one specific adenosine on the 28S rRNA.SUBUNIT:Heterotetramer of two A and two B chains.DOMAIN:The B chain is composed of two domains, each domain consists of 3 homologous subdomains (alpha, beta, gamma).MISCELLANEOUS:Induces cytokine production and proliferation of splenocytes and thymocytes in mice.SIMILARITY:In the N-terminal section; belongs to the ribosome- inactivating protein family. Type 2 RIP subfamily.SIMILARITY:Contains 2 ricin B-type lectin domains. |
