Asymmetric/Biological Unit(hide GO term definitions)

Chain A (TEN1_SCHPO | P0C5Y7)

molecular function
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0043047	single-stranded telomeric DNA binding	Interacting selectively and non-covalently with single-stranded telomere-associated DNA.
biological process
	GO:0016233	telomere capping	A process in which telomeres are protected from degradation and fusion, thereby ensuring chromosome stability by protecting the ends from both degradation and from being recognized as damaged DNA. May be mediated by specific single- or double-stranded telomeric DNA binding proteins.
cellular component
	GO:1990879	CST complex	A complex formed by the association of Cdc13 (CTC1 in mammals) with Stn1 in yeast (OBFC1 in mammals) and Ten1 protein (also TEN1 in mammals) with single-stranded telomeric DNA. The CST complex plays a role in telomere protection.
	GO:0005694	chromosome	A structure composed of a very long molecule of DNA and associated proteins (e.g. histones) that carries hereditary information.
	GO:0000781	chromosome, telomeric region	The terminal region of a linear chromosome that includes the telomeric DNA repeats and associated proteins.
	GO:0000784	nuclear chromosome, telomeric region	The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins.
	GO:0005724	nuclear telomeric heterochromatin	Heterochromatic regions of the chromosome found at the telomeres of a chromosome in the nucleus.
	GO:0005634	nucleus	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
