Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (ACD_HUMAN | Q96AP0)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0070182    DNA polymerase binding    Interacting selectively and non-covalently with a DNA polymerase.
    GO:0044877    macromolecular complex binding    Interacting selectively and non-covalently with any macromolecular complex.
    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:0042162    telomeric DNA binding    Interacting selectively and non-covalently with a telomere, a specific structure at the end of a linear chromosome required for the integrity and maintenance of the end.
biological process
    GO:0030326    embryonic limb morphogenesis    The process, occurring in the embryo, by which the anatomical structures of the limb are generated and organized. A limb is an appendage of an animal used for locomotion or grasping.
    GO:0070200    establishment of protein localization to telomere    The directed movement of a protein to a specific location in the telomeric region of a chromosome.
    GO:0006886    intracellular protein transport    The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
    GO:0032211    negative regulation of telomere maintenance via telomerase    Any process that stops, prevents, or reduces the frequency, rate or extent of the addition of telomeric repeats by telomerase.
    GO:0060381    positive regulation of single-stranded telomeric DNA binding    Any process that increases the frequency, rate or extent of single-stranded telomeric DNA binding.
    GO:0051973    positive regulation of telomerase activity    Any process that activates or increases the frequency, rate or extent of telomerase activity, the catalysis of the reaction: deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
    GO:0032212    positive regulation of telomere maintenance via telomerase    Any process that activates or increases the frequency, rate or extent of the addition of telomeric repeats by telomerase.
    GO:0031848    protection from non-homologous end joining at telomere    A process that prevents non-homologous end joining at telomere, thereby ensuring that telomeres do not fuse.
    GO:0070198    protein localization to chromosome, telomeric region    Any process in which a protein is transported to, or maintained at, the telomeric region of a chromosome.
    GO:0035282    segmentation    The regionalization process that divides an organism or part of an organism into a series of semi-repetitive parts, or segments, often arranged along a longitudinal axis.
    GO:0001501    skeletal system development    The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).
    GO:0032202    telomere assembly    A cellular process that results in the aggregation, arrangement and bonding together of a set of components to form a telomere at a non-telomeric double-stranded DNA end. A telomere is a terminal region of a linear chromosome that includes telomeric DNA repeats and associated proteins.
    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.
    GO:0000723    telomere maintenance    Any process that contributes to the maintenance of proper telomeric length and structure by affecting and monitoring the activity of telomeric proteins, the length of telomeric DNA and the replication and repair of the DNA. These processes includes those that shorten, lengthen, replicate and repair the telomeric DNA sequences.
    GO:0007004    telomere maintenance via telomerase    The maintenance of proper telomeric length by the addition of telomeric repeats by telomerase.
    GO:0001655    urogenital system development    The process whose specific outcome is the progression of the urogenital system over time, from its formation to the mature structure.
cellular component
    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:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0000784    nuclear chromosome, telomeric region    The terminal region of a linear nuclear chromosome that includes the telomeric DNA repeats and associated proteins.
    GO:0000783    nuclear telomere cap complex    A complex of DNA and protein located at the end of a linear chromosome in the nucleus that protects and stabilizes a linear chromosome.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    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.
    GO:0070187    shelterin complex    A nuclear telomere cap complex that is formed by the association of telomeric ssDNA- and dsDNA-binding proteins with telomeric DNA, and is involved in telomere protection and recruitment of telomerase. The complex is known to contain TERF1, TERF2, POT1, RAP1, TINF2 and ACD in mammalian cells, and Pot1, Tpz1, Rap1, Rif1, Rif2 and Taz1 in Schizosaccharomyces. Taz1 and Rap1 (or their mammalian equivalents) form a dsDNA-binding subcomplex, Pot1 and Tpz1 form an ssDNA-binding subcomplex, and the two subcomplexes are bridged by Poz1, which acts as an effector molecule along with Ccq1.
