Cd81 - CD81 antigen Gene

Also Known as Tapa1; Tapa-1; Tspan28

Species: Mus musculus

Gene Type: protein coding

Gene ID: 12520

Summary

Predicted to enable Cholesterol binding activity; signaling receptor binding activity; and virus receptor activity. Involved in several processes, including cellular response to low-density lipoprotein particle stimulus; positive regulation of immune response; 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. Orthologous to human CD81 (CD81 molecule). [provided by Alliance of Genome Resources, Apr 2022]
