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 ups
tream 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). [provided by Alliance of Genome Resources, Jul 2025]
Involved in modulation of chemical synaptic transmission. Acts upstream of or within regulation of cell motility. Located in axon and synapse. Is expressed in several structures, including branchial arch; cardiac muscle tissue; central nervous system; epithelium; and sensory organ. Orthologous to hu
