Dubious open reading frame unlikely to encode a functional protein, based on available experimental and comparative sequence data (106 aa)

Transcription factor targeting filamentation genes and Ty1 expression; Ste12p activation of most filamentation gene promoters depends on Tec1p and Tec1p transcriptional activity is dependent on its association with Ste12p; binds to TCS elements upst /.../f filamentation genes, which are regulated by Tec1p/Ste12p/Dig1p complex; competes with Dig2p for binding to Ste12p/Dig1p; positive regulator of chronological life span; TEA/ATTS DNA-binding domain family member; TEC1 is involved in the activation of TY1 and TY1- mediated gene expression. It is not involved in mating or sporulation processes (486 aa)

Cyclin-dependent protein kinase, component of RNA polymerase II holoenzyme; involved in phosphorylation of the RNA polymerase II C-terminal domain; involved in glucose repression; Component of the SRB8-11 complex. The SRB8-11 complex is a regulatory module of the Mediator complex which is itself involved in regulation of basal and activated RNA polymerase II- dependent transcription. The SRB8-11 complex may be involved in the transcriptional repression of a subset of genes regulated by Mediator. It may inhibit the association of the Mediator complex with RNA polymerase II to form the h [...] (555 aa)

Transcription factor involved in regulation of invasive growth and starch degradation; controls the activation of MUC1 and STA2 in response to nutritional signals; Transcription factor that regulates pseudohyphal differentiation, invasive growth, floculation, adhesion and starch metabolism in response to nutrient availability (758 aa)

Essential protein required for maturation of 18S rRNA; null mutant is sensitive to hydroxyurea and is delayed in recovering from alpha-factor arrest; green fluorescent protein (GFP)-fusion protein localizes to the nucleolus; Involved in rRNA processing. Required growth at elevated temperatures, resistance to hydroxyurea and for cell cycle progression (233 aa)

GPI-anchored cell surface glycoprotein (flocculin); required for pseudohyphal formation, invasive growth, flocculation, and biofilms; transcriptionally regulated by the MAPK pathway (via Ste12p and Tec1p) and the cAMP pathway (via Flo8p); required f /.../ formation of fibrous interconnections between cells in a colony of a wild S. cerevisiae strain; Cell wall protein that participates in adhesive cell- cell interactions during yeast flocculation, a reversible, asexual and Ca(2+)-dependent process in which cells adhere to form aggregates (flocs) consisting of thousands of cells. Also in [...] (1367 aa)

Basic leucine zipper (bZIP) transcription factor; physically interacts with the Tup1-Cyc8 complex and recruits Tup1p to its targets; overexpression increases sodium and lithium tolerance; computational analysis suggests a role in regulation of expre /.../of genes involved in carbohydrate metabolism; Transcription activator involved in the regulation of genes expressed in response to environmental changes and metabolic requirements. According to genome-wide promoter binding and gene expression studies it regulates, among others, genes involved in ribosome biogenesis, protein synthesis, [...] (383 aa)

Ammonium permease involved in regulation of pseudohyphal growth; belongs to a ubiquitous family of cytoplasmic membrane proteins that transport only ammonium (NH4+); expression is under the nitrogen catabolite repression regulation; Transporter for ammonium (both charged and uncharged NH3 and NH4) to use as a nitrogen source. The affinity of MEP2 is about twenty times higher than that of MEP1. MEP3 has the lowest affinity. Under ammonium limitation acts as an ammonium sensor, generating a signal that leads to pseudohyphal growth (499 aa)
