STRINGSTRING
LAS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"LAS1" - Protein required for pre-rRNA processing at both ends of ITS2 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

LAS1Protein required for pre-rRNA processing at both ends of ITS2; may coordinate the action of the Rat1p-Rai1p exoRNAse; required for the G1/S transition of the cell cycle; human ortholog is Las1L; mutants require the SSD1-v allele for viability; Regulates cell surface growth, bud formation and morphogenesis. May act indirectly by regulating factor(s) involved in these processes (502 aa)    
Predicted Functional Partners:
GRC3
Polynucleotide kinase present on rDNA that is required for efficient transcription termination by RNA polymerase I; required for cell growth; mRNA is cell-cycle regulated; Polynucleotide 5’-kinase involved in rRNA processing. Required for the efficient termination by RNA polymerase I and the processing of the IST2 pre-rRNA internal transcribed spacer localized between the 5.8S and 25S rRNAs. May act by maintaining the phosphorylated status of the downstream RNT1 cleavage product, which in turn allows the torpedo activity of RAT1 to efficiently terminate Pol I transcription. In vitro, d [...] (632 aa)
