Tpcn1 Gene Summary [Rat]
Predicted to enable several functions, including monoatomic cation channel activity; phosphatidylinositol-3,5-bisphosphate binding activity; and protein homodimerization activity. Predicted to be involved in endocytosis involved in viral entry into host cell; positive regulation of autophagy; and sodium ion transmembrane transport. Predicted to be located in early endosome membrane; endolysosome; and recycling endosome membrane. Predicted to be part of monoatomic ion channel complex. Predicted to be active in endosome membrane and lysosomal membrane. Orthologous to human TPCN1 (two pore segment channel 1). [provided by Alliance of Genome Resources, Jul 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 Tpcn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
