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
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
- STP2 and its paralog STP1 encode transcription factors that are members of the C2H2 zinc finger class. Stp1p and Stp2p act independently of each other but have redundant roles in regulation of genes encoding amino acid and peptide permeases, including AGP1, BAP2, BAP3, DIP5, GNP1, MUP1, TAT1 and TAT2, and PTR2. In response to the presence of extracellular amino acids, they bind to UAS-aa elements in the promoters of their target genes and activate transcription. Stp1p and Stp2p are among several transcription factors involved in nitrogen source utilization (including Uga3p, Dal82p, Stp1p, and Stp2p) whose function depends on cooperation with the transcription factor Dal81p. In the case of Stp1p and Stp2p, Dal81p facilitates their promoter binding and contributes to transcription activation, but is not absolutely required for activity. The involvement of Dal81p in pathways for utilization of several different nitrogen sources allows the cell to integrate the disparate nutritional signals and to induce different pathways according to availability of each source. Activity of Stp1p and Stp2p is regulated by the SPS-sensing pathway, so-called because its first step is sensing by a plasma membrane complex composed of Ssy1p, Ptr3, and Ssy5p. In the absence of extracellular amino acids, Stp1p and Stp2p exist as precursor proteins that are largely cytoplasmic. The small amounts of precursor that do enter the nucleus are prevented from binding to target promoters by three nuclear inner membrane proteins, Asi1p, Asi2p, and Asi3p. Under inducing conditions, the proteolytic activity of Ssy5p is activated and it cleaves inhibitory N-terminal domains from Stp1p and Stp2p. The mature forms of Stp1p and Stp2p are able to enter the nucleus and activate transcription.
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).
