STRINGSTRING
ELF1 protein (Saccharomyces cerevisiae) - STRING interaction network
"ELF1" - Transcription elongation factor with a conserved zinc finger domain 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

ELF1Transcription elongation factor with a conserved zinc finger domain; implicated in the maintenance of proper chromatin structure in actively transcribed regions; deletion inhibits Brome mosaic virus (BMV) gene expression; Transcription elongation factor implicated in the maintenance of proper chromatin structure in actively transcribed regions (145 aa)    
Predicted Functional Partners:
CTK1
Catalytic (alpha) subunit of C-terminal domain kinase I (CTDK-I); phosphorylates both RNA pol II subunit Rpo21p to affect transcription and pre-mRNA 3’ end processing, and ribosomal protein Rps2p to increase translational fidelity; similar to the Dr /.../la dCDK12 and human CDK12 and probably CDK13; Catalytic subunit of the CTDK-I complex, which hyperphosphorylates the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit. CTDK-I phosphorylates ’Ser-5’ if the CTD substrate is not phosphorylated at ’Ser-5’, but will phosphorylate ’Ser-2’ of a CTD substrate [...] (528 aa)

POB3
Subunit of the heterodimeric FACT complex (Spt16p-Pob3p), which associates with chromatin via interaction with Nhp6Ap and Nhp6Bp, and reorganizes nucleosomes to facilitate access to DNA by RNA and DNA polymerases; Component of the FACT complex, a general chromatin factor that acts to reorganize nucleosomes. The FACT complex is involved in multiple processes that require DNA as a template such as mRNA elongation, DNA replication and DNA repair. During transcription elongation the FACT complex acts as a histone chaperone that both destabilizes and restores nucleosomal structure. It facil [...] (552 aa)

CTK3
Gamma subunit of C-terminal domain kinase I (CTDK-I), which phosphorylates both RNA pol II subunit Rpo21p to affect transcription and pre-mRNA 3’ end processing, and ribosomal protein Rps2p to increase translational fidelity; Gamma subunit of the CTDK-I complex, which hyperphosphorylates the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit. CTDK-I phosphorylates ’Ser-5’ if the CTD substrate is not phosphorylated at ’Ser-5’, but will phosphorylate ’Ser-2’ of a CTD substrate if ’Ser-5’ is already phosphorylated. CTDK-I is also more reactive toward subs [...] (296 aa)

CTK2
Beta subunit of C-terminal domain kinase I (CTDK-I), which phosphorylates both RNA pol II subunit Rpo21p to affect transcription and pre-mRNA 3’ end processing, and ribosomal protein Rps2p to increase translational fidelity; Cyclin subunit of the CTDK-I complex, which hyperphosphorylates the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit. CTDK-I phosphorylates ’Ser-5’ if the CTD substrate is not phosphorylated at ’Ser-5’, but will phosphorylate ’Ser-2’ of a CTD substrate if ’Ser-5’ is already phosphorylated. CTDK-I is also more reactive toward subs [...] (323 aa)

SPT4
Protein involved in the regulating Pol I and Pol II transcription, pre-mRNA processing, kinetochore function, and gene silencing; forms a complex with Spt5p; The SPT4-SPT5 complex mediates both activation and inhibition of transcription elongation, and plays a role in pre- mRNA processing. The complex seems to be important for the stability of the RNA polymerase II elongation machinery on the chromatin template but not for the inherent ability of this machinery to translocate down the gene. Structural and functional component of the centromeric and heterochromatic loci linking chromati [...] (102 aa)
