Primary Identifier | MGI:1096398 | Organism | mouse, laboratory |
Chromosome | 7 | NCBI Gene Number | 12520 |
Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Predicted to enable cholesterol binding activity; signaling receptor binding activity; and virus receptor activity. Involved in several processes, including positive regulation of immune response; positive regulation of receptor clustering; and syncytium formation by plasma membrane fusion. Acts upstream of or within regulation of cell motility. Located in membrane. Is expressed in several structures, including alimentary system; extraembryonic component; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in common variable immunodeficiency 6. Orthologous to human CD81 (CD81 molecule). PHENOTYPE: Homozygotes for targeted null mutations exhibit altered antibody responses to specific antigens, reductions in peritoneal B-1 cell numbers and IL4 production, increased plasma IgA and IgM levels, and enlarged brains with more astrocytes and microglia.
