Siglec1 Gene Summary [Rat]
Predicted to enable virion binding activity. Predicted to be involved in clathrin-dependent endocytosis of virus by host cell; negative regulation of phagocytosis; and negative regulation of type I interferon production. Predicted to act upstream of or within positive regulation of T cell apoptotic process and positive regulation of extrinsic apoptotic signaling pathway. Predicted to be located in endocytic vesicle. Predicted to be active in early endosome; late endosome; and plasma membrane. Orthologous to human SIGLEC1 (sialic acid binding Ig like lectin 1). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Siglec1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
