Glc7p is found in a variety of cellular locations, as dictated by its various functions and targeting partners, including spindle pole bodies from start of anaphase until cytokinesis, the bud neck ring after anaphase, the base of mating projections in alpha-factor treated cells, and in the nucleus with high concentrations in the nucleolus throughout the mitotic cell cycle (34). Glc7p requires Sds22p for its for normal nuclear localization during mitosis (36, 20), and requires Gip1p for its meiotic nuclear localization and involvement in the regulation of septin organization and spore wall formation (41).While glc7 null mutants are inviable, reduction-of-function mutations result in a wide range of phenotypes. glc7-1 mutants display a severe defect in glycogen accumulation but normal glucose repression, whereas glc7-T152K mutations do not prevent glycogen accumulation, but do relieve glucose repression (12). At restrictive temperatures, glc7-10 mutants display a high frequency of chromosome loss, hyperphosphorylation of Cbf2p (16), a high proportion of budded cells with an unmigrated nucleus, duplicated spindle pole bodies, a short spindle, delocalized cortical actin and 2C DNA content (19). glc7-109 mutants display a dominant hyperglycogen defect and recessive ion and drug sensitivity (23). glc7-129, glc7-131, and glc7-127 mutants display elevated levels of mitotic histone H3 phosphorylation (26), and glc7-129 cells also display a G2/M cell cycle arrest (27). glc7Y-170 mutants display a defect in the G2/M phase of the cell cycle (30). GLC7 mutations have also been associated with defects in premeiotic DNA synthesis and sporulation (21) and depletion of Glc7p is associated with G1 arrest (21). Overexpression of GLC7 results in chromosome missegregation (28, 25), growth defects, aberrant bud morphology (40), and mitotic delay with increased numbers of large budded cells which are blocked in mitosis (40).

Amino acid sequences of catalytic subunits of type 1 protein phosphatase are highly conserved across many species (21), such that GLC7 displays similarity to many PP1 eukaryotic counterparts, including Schizosaccharomyces pombe dis2, Drosophila melanogaster and rabbit protein phosphatase 1 catalytic subunits (4), and human PPP1CA and PPP1CB, PPP1CC (47, 17).", "date_edited": "2005-11-01"}, "literature_overview": {"primary_count": 140, "additional_count": 101, "review_count": 106, "go_count": 23, "phenotype_count": 16, "disease_count": 1, "interaction_count": 169, "regulation_count": 14, "ptm_count": 12, "funComplement_count": 4, "htp_count": 29, "total_count": 459}, "disease_overview": {"manual_disease_terms": [{"annotation_type": "manually curated", "qualifiers": [null], "term": {"link": "/disease/DOID:162", "display_name": "cancer"}, "evidence_codes": [{"display_name": "ISS", "link": "http://wiki.geneontology.org/index.php/Inferred_from_Sequence_or_structural_Similarity_(ISS)"}, {"display_name": "IGI", "link": "http://wiki.geneontology.org/index.php/Inferred_from_Genetic_Interaction_(IGI)"}]}], "htp_disease_terms": [], "computational_annotation_count": 0, "date_last_reviewed": "2017-04-12", "paragraph": "Yeast GLC7 is homologous to human PPP1CA and PPP1CC, and has been used to study cancer"}, "ecnumbers": [{"display_name": "3.1.3.16", "link": "/ecnumber/EC:3.1.3.16"}], "URS_ID": null, "main_strain": "S288C", "regulation_overview": {"regulator_count": 8, "target_count": 12}, "reference_mapping": {"615562": 1, "616972": 2, "646653": 3, "634631": 4, "558002": 5, "486994": 6, "394369": 7, "392840": 8, "490098": 9, "315954": 10, "309347": 11, "606544": 12, "536225": 13, "580237": 14, "543278": 15, "617553": 16, "553934": 17, "635763": 18, "627454": 19, "564057": 20, "635404": 21, "554140": 22, "562088": 23, "539757": 24, "630470": 25, "606778": 26, "617568": 27, "635721": 28, "586595": 29, "632154": 30, "608941": 31, "548131": 32, "528906": 33, "615906": 34, "634305": 35, "644960": 36, "561063": 37, "631930": 38, "619649": 39, "616569": 40, "571974": 41, "554293": 42, "600431": 43, "546599": 44, "549441": 45, "545125": 46, "576410": 47, "635452": 48, "636574": 49}, "history": [{"category": "Name", "history_type": "LSP", "note": "Name: CID1", "date_created": "2010-02-16", "references": [{"id": 635452, "display_name": "Neigeborn L and Carlson M (1987)", "citation": "Neigeborn L and Carlson M (1987) Mutations causing constitutive invertase synthesis in yeast: genetic interactions with snf mutations.

Gene Ontology Details

Gene Ontology

GO Annotations consist of four mandatory components: a gene product, a term from one of the three Gene Ontology (GO) controlled vocabularies (Molecular Function, Biological Process, and Cellular Component), a reference, and an evidence code. SGD has manually curated and high-throughput GO Annotations, both derived from the literature, as well as computational, or predicted, annotations. Click "Gene Ontology Details" to view all GO information and evidence for this locus as well as biological processes it shares with other genes.

Phenotype Details

Phenotype

Phenotype annotations for a gene are curated single mutant phenotypes that require an observable (e.g., "cell shape"), a qualifier (e.g., "abnormal"), a mutant type (e.g., null), strain background, and a reference. In addition, annotations are classified as classical genetics or high-throughput (e.g., large scale survey, systematic mutation set). Whenever possible, allele information and additional details are provided.

Expression Details

Expression

Expression data are derived from records contained in the Gene Expression Omnibus (GEO), and are first log2 transformed and normalized. Referenced datasets may contain one or more condition(s), and as a result there may be a greater number of conditions than datasets represented in a single clickable histogram bar. The histogram division at 0.0 separates the down-regulated (green) conditions and datasets from those that are up-regulated (red).
