ISR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ISR1" - Predicted protein kinase, overexpression causes sensitivity to staurosporine, which is a potent inhibitor of protein kinase C 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

ISR1Predicted protein kinase, overexpression causes sensitivity to staurosporine, which is a potent inhibitor of protein kinase C; Probable serine/threonine protein kinase which may function redundantly with MPK1-independent branch of the PCK1 pathway that is presumed to be required for the tolerance to high temperatures and staurosporine (443 aa)    
Predicted Functional Partners:
Positive regulator of the Gcn2p kinase activity, forms a complex with Gcn20p; proposed to stimulate Gcn2p activation by an uncharged tRNA; Acts as a positive activator of the GCN2 protein kinase activity in response to amino acid starvation (PubMed-8497269, PubMed-24333428). Component of the GCN1-GCN20 complex that forms a complex with GCN2 on translating ribosomes; during this process, GCN1 seems to act as a chaperone to facilitate delivery of uncharged tRNAs that enter the A site of ribosomes to the tRNA- binding domain of GCN2, and hence stimulating GCN2 kinase activity (PubMed-7621 [...] (2672 aa)
Highly-acidic cytoplasmic RWD domain-containing protein of unknown function; forms a complex with Rbg2p; interacts with Rbg1p and Gcn1p; associates with translating ribosomes; putative intrinsically unstructured protein; Acts as a negative regulator of the GCN2 kinase activity by disrupting the GCN1-GCN2 interaction in amino acid-starved cells (PubMed-19448108) (265 aa)
Protein kinase; implicated in proteasome function; interacts with TORC1, Ure2 and Gdh2; overexpression leads to hypersensitivity to rapamycin and nuclear accumulation of Gln3; epitope-tagged protein localizes to the cytoplasm; Serine/threonine-protein kinase involved in the phosphorylation of the NAD(+)-dependent glutamate dehydrogenase GDH2. When overexpressed, confers hypersensitivity to rapamycin and induces rapid nuclear accumulation of GLN3 to activate the transcription of nitrogen-regulated genes (928 aa)
Serine/threonine protein kinase; inhibits pheromone induced signaling downstream of MAPK, possibly at the level of the Ste12p transcription factor; Protein kinase that functions as regulator in the pheromone-induced mating pathway downstream of mitogen-activated protein kinase (MAPK) FUS3. Diminishes transcriptional induction of genes in response to pheromone signaling (518 aa)
Protein kinase of unknown cellular role; binds phosphatidylinositols and cardiolipin in a large-scale study; Putative serine/threonine-protein kinase (901 aa)
Putative serine/threonine protein kinase with unknown cellular role (724 aa)
Putative serine/threonine kinase; expression is induced during mild heat stress; deletion mutants are hypersensitive to copper sulphate and resistant to sorbate; interacts with an N-terminal fragment of Sst2p (667 aa)
Nonessential serine/threonine protein kinase; possible role in DNA damage response; This protein is probably a serine/threonine protein kinase (435 aa)
Protein serine/threonine kinase essential for cell wall remodeling during growth; localized to sites of polarized growth and the mother-daughter bud neck; homolog of the alpha, beta, and gamma isoforms of mammalian protein kinase C (PKC); Required for cell growth and for the G2->M transition of the cell division cycle. Mediates a protein kinase cascade; it activates BCK1 which itself activates MKK1/MKK2 (1151 aa)
Cell-cycle checkpoint serine-threonine kinase required for DNA damage-induced transcription of certain target genes, phosphorylation of Rad55p and Sml1p, and transient G2/M arrest after DNA damage; also regulates postreplicative DNA repair; Transducer of the DNA damage signal. Phosphorylates SML1 on serine residues. Cooperates with the PAN deadenylation complex in the regulation of RAD5 mRNA levels and cell survival in response to replicational stress (513 aa)
