Primary Identifier | MGI:88322 | Organism | mouse, laboratory |
Chromosome | 7 | NCBI Gene Number | 12483 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables CD4 receptor binding activity; protein phosphatase binding activity; and sialic acid binding activity. Involved in several processes, including negative regulation of calcium-mediated signaling; negative regulation of immunoglobulin production; and regulation of B cell proliferation. Located in external side of plasma membrane and neuronal cell body membrane. Is expressed in several structures, including alimentary system; brain; hemolymphoid system gland; liver and biliary system; and reproductive system. Human ortholog(s) of this gene implicated in diffuse large B-cell lymphoma. Orthologous to human CD22 (CD22 molecule). PHENOTYPE: Homozygous null mice have reduced mature B cell numbers with altered proliferation kinetics and reduced antibody production to T cell independent antigens. [provided by MGI curators] |
