GO:0002481 | antigen processing and presentation of exogenous protein antigen via MHC class Ib, TAP-dependent
Description: The process in which an antigen-presenting cell expresses a peptide antigen of exogenous origin on its cell surface in association with an MHC class Ib protein complex following intracellular transport via a TAP (transporter associated with antigen processing) pathway.

GO:0044403 | biological process involved in symbiotic interaction
Description: A process carried out by gene products in an organism that enable the organism to engage in a symbiotic relationship, a more or less intimate association, with another organism. The various forms of symbiosis include parasitism, in which the association is disadvantageous or destructive to one of the organisms; mutualism, in which the association is advantageous, or often necessary to one or both and not harmful to either; and commensalism, in which one member of the association benefits while the other is not affected. However, mutualism, parasitism, and commensalism are often not discrete categories of interactions and should rather be perceived as a continuum of interaction ranging from parasitism to mutualism. In fact, the direction of a symbiotic interaction can change during the lifetime of the symbionts due to developmental changes as well as changes in the biotic/abiotic environment in which the interaction occurs. Microscopic symbionts are often referred to as endosymbionts.

GO:0005868 | cytoplasmic dynein complex
Description: Any dynein complex with a homodimeric dynein heavy chain core that catalyzes movement along a microtubule. Cytoplasmic dynein complexes participate in many cytoplasmic transport activities in eukaryotes, such as mRNA localization, intermediate filament transport, nuclear envelope breakdown, apoptosis, transport of centrosomal proteins, mitotic spindle assembly, virus transport, kinetochore functions, and movement of signaling and spindle checkpoint proteins. Some complexes participate in intraflagellar transport. Subunits associated with the dynein heavy chain mediate association between dynein heavy chain and cargoes, and may include light chains and light intermediate chains.

GO:0006311 | meiotic gene conversion
Description: The cell cycle process in which genetic information is transferred from one helix to another. It often occurs in association with general genetic recombination events, and is believed to be a straightforward consequence of the mechanisms of general recombination and DNA repair. For example, meiosis might yield three copies of the maternal version of an allele and only one copy of the paternal allele, indicating that one of the two copies of the paternal allele has been changed to a copy of the maternal allele.

GO:0070187 | shelterin complex
Description: 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 Saccharomyces. 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.

GO:0120114 | Sm-like protein family complex
Description: A protein complex containing members of the Like-Sm family of proteins, which includes both the Sm proteins and the Lsm proteins, and which generally form hexameric or heptameric ring structures which bind to RNA. While some of these ring complexes may form independently of RNA, many only form in association with their target RNA. In addition to Lsm-family proteins, many of these complexes contain additional protein members. Members of this family of complexes include the snRNPs which comprise the majority of the spliceosome. Others are involved in the 5' to 3' degradation pathways of mRNAs in the cytoplasm and of unspliced transcripts in the nucleus, as well as other diverse roles.
