Predicted to enable identical protein binding activity; mannose binding activity; and virus receptor activity. Predicted to be involved in several processes, including B cell adhesion; positive regulation of T cell proliferation; and positive regulation of viral life cycle. Predicted to act upstream of or within several processes, including defense response to bacterium; endocytosis; and regulation of T cell proliferation. Predicted to be located in plasma membrane. Predicted to be active in external side of plasma membrane. Human ortholog(s) of this gene implicated in Coronavirus infectious disease; aspergillosis; dengue disease (multiple); human immunodeficiency virus infectious disease (multiple); and tuberculosis (multiple). Orthologous to human CD209 (CD209 molecule). [provided by Alliance of Genome Resources, Apr 2022]
