PHD1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PHD1" - Transcriptional activator that enhances pseudohyphal growth in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

Gene Fusion
PHD1Transcriptional activator that enhances pseudohyphal growth; physically interacts with the Tup1-Cyc8 complex and recruits Tup1p to its targets; regulates expression of FLO11, an adhesin required for pseudohyphal filament formation; similar to StuA, /.../nidulans developmental regulator; potential Cdc28p substrate; Putative transcription factor that functions in pseudohyphal growth (366 aa)    
Predicted Functional Partners:
Transcription factor that is activated by a MAPK signaling cascade; activates genes involved in mating or pseudohyphal/invasive growth pathways; cooperates with Tec1p transcription factor to regulate genes specific for invasive growth; Binds to the DNA sequence mediating pheromone induction (called the pheromone response element = PRE) which is found in the upstream control region of several a-, alpha- and haploid- specific genes. Involved in mating of haploids and in pseudohyphae formation in diploids (688 aa)
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)
General repressor of transcription, forms complex with Cyc8p, involved in the establishment of repressive chromatin structure through interactions with histones H3 and H4, appears to enhance expression of some genes; Acts as component of the CYC8-TUP1 corepressor complex which is involved in the repression of many genes in a wide variety of physiological processes including heme-regulated and catabolite repressed genes. May also be involved in the derepression of at least some target genes. The complex is recruited to target genes by interaction with DNA-bound transcriptional repressor [...] (713 aa)
