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.

Complex
Macromolecular complex annotations are imported from the Complex Portal. These annotations have been derived from physical molecular interaction evidence extracted from the literature and cross-referenced in the entry, or by curator inference from information on homologs in closely related species or by inference from scientific background.
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.

- Summary
- TEC1/YBR083W is a non-essential gene in reference strain S288C; null mutants are viable and show decreased competitive fitness, decreased chronological lifespan, reduced utilization of glucose, ammonium, and allantoin, abnormal subcellular morphology, decreased transposable element transposition, and decreased resistance to rapamycin. In Sigma1278b, the null abolishes invasive growth, decreases filamentous growth and biofilm formation, delays budding, and causes abnormal colony appearance. Overexpression in S288C causes abnormal nuclear morphology, abnormal cell cycle progression, and reduced competitive fitness; in Sigma1278b it increases invasive and filamentous growth.

- Summary
- TEC1 encodes a helix-turn-helix transcription factor of the homeodomain family involved in the regulation of genes involved in the invasive/pseudohyphal growth cascade. Tec1p belongs to the TEA domain (TEAD) family of regulators that control cellular development in many eukaryotes, and recognizes a motif called the TEA/ATTS consensus sequence (TCS), 5'-RCATTCCY-3'. Tec1p and Ste12p can physically interact and are a model for studying the mechanisms of combinatorial and promoter-specific target gene control. The association of a pheromone-responsive element (PRE), containing the consensus sequence 5'-TGAAACA-3' which is recognized by Ste12p, and a TCS has been designated a filamentous responsive element (FRE) and allows binding of a Tec1p-Ste12p heterodimer to activate gene expression. However, Tec1p-Ste12p heterodimers can also regulate target genes via single TCS elements, with Tec1p providing the DNA binding and Ste12p the transcriptional activation. Tec1p can also activate target genes independently of Ste12p. Tec1p is required for FLO11 expression and for vegetative adhesion. The FLO11 promoter contains both FREs and TCS elements and is bound by Tec1p and Ste12p, though Tec1p is also able to activate FLO11 expression by without Ste12p. During vegetative growth, Dig1p and Dig2p directly inhibit the transcriptional activity of the Tec1p-Ste12p heterodimer. In response to pheromone, the inhibitory functions of Dig1p and Dig2p are relieved by phosphorylation through the mating-specific MAPKs Fus3p and Kss1p. Fus3p also phosphorylates Tec1p, which induces its degradation by the proteasome and abrogating FLO11 expression, thereby maintaining signaling specificity during the pheromone response.
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).
