STRINGSTRING
FHL1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FHL1" - Regulator of ribosomal protein transcription in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

FHL1Regulator of ribosomal protein transcription; has forkhead associated domain that binds phosphorylated proteins; also has forkhead DNA-binding domain but does not bind DNA in vitro; suppresses RNA pol III and splicing factor prp4 mutants; Controls the pre-rRNA processing machinery in conjunction with IFH1. Presumably acts as a transcriptional regulator of genes specifically involved in that process. IFH1 convert FHL1 from a repressor to an activator (936 aa)    
Predicted Functional Partners:
IFH1
Coactivator that regulates transcription of ribosomal protein (RP) genes; recruited to RP gene promoters during optimal growth conditions via Fhl1p; subunit of CURI, a complex that coordinates RP production and pre-rRNA processing; Controls the pre-rRNA processing machinery in conjunction with FHL1. Could convert FHL1 from a repressor to an activator (1085 aa)

SCH9
Protein kinase involved in transcriptional activation of osmostress-responsive genes; regulates G1 progression, cAPK activity, nitrogen activation of the FGM pathway; involved in life span regulation; homologous to mammalian Akt/PKB; Protein kinase that is part of growth control pathway which is at least partially redundant with the cAMP pathway. Regulates both BCY1 phosphorylation and MPK1 activity (PubMed-20702584). Regulates ribosome biogenesis, translation initiation, and entry into stationary phase in a TORC1-dependent manner (PubMed-17560372) (824 aa)

RAP1
DNA-binding protein involved in either activation or repression of transcription, depending on binding site context; also binds telomere sequences and plays a role in telomeric position effect (silencing) and telomere structure; Essential regulatory protein in yeast whose DNA-binding sites are found at three types of chromosomal elements- promoters, silencers, and telomeres. RAP1 is also involved in the regulation of telomere structure, where its binding sites are found within the terminal poly[C(1-3)A] sequences. The opposite regulatory functions of RAP1 are not intrinsic to its bindi [...] (827 aa)

YPK2
Protein kinase with similarity to serine/threonine protein kinase Ypk1p; functionally redundant with YPK1 at the genetic level; participates in a signaling pathway required for optimal cell wall integrity; homolog of mammalian kinase SGK; May act as a downstream kinase in the sphingolipid- mediated signaling pathway. Plays an essential role in the proliferation of yeast cells. Involved in a signaling pathway, required for optimal cell wall integrity, that acts in parallel with the PKC1-SLT2-dependent pathway. A substrate of TOR complex 2 (TORC2) and required for TORC2 to regulate spati [...] (677 aa)

YPK1
Serine/threonine protein kinase that phosphorylates and downregulates flippase activator Fpk1p; mutations affect receptor-mediated endocytosis and sphingolipid-mediated and cell integrity signaling pathways; homolog of mammalian kinase SGK; Plays an essential role in the proliferation of yeast cells. Involved in a signaling pathway, required for optimal cell wall integrity, that acts in parallel with the PKC1-SLT2-dependent pathway. Downstream kinase in the sphingolipid-mediated signaling pathway. Its phosphorylation is regulated by the intracellular sphingolipid concentration. Coopera [...] (680 aa)

YPK3
An AGC kinase phosphorylated by cAMP-dependent protein kinase (PKA) in a TORC1-dependent manner; AGC kinase which plays a role in TOR complex 1 (TORC1) signaling pathway which mediates temporal control of cell growth in response to nutrients (PubMed-11062466). Required for phosphorylation of ribosomal protein S6 (RPS6A/RPS6B) at ’Ser-232’ and ’Ser-233’ (PubMed-25767889) (525 aa)

NDD1
Transcriptional activator essential for nuclear division; localized to the nucleus; essential component of the mechanism that activates the expression of a set of late-S-phase-specific genes; Transcription activator involved in G2/M transcription through its association with FKH2 (554 aa)

HST1
NAD(+)-dependent histone deacetylase; essential subunit of the Sum1p/Rfm1p/Hst1p complex required for ORC-dependent silencing and mitotic repression; non-essential subunit of the Set3C deacetylase complex; involved in telomere maintenance; NAD-dependent histone deacetylase involved in telomeric silencing. Histone deacetylase proteins act via the formation of large multiprotein complexes that are responsible for the deacetylation of lysine residues on the N-terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation gives a tag for epigenetic repression and plays an [...] (503 aa)
