STRINGSTRING
SIG2 protein (Arabidopsis thaliana) - STRING interaction network
"SIG2" - RNApolymerase sigma subunit 2 in Arabidopsis thaliana
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

SIG2RNApolymerase sigma subunit 2; Required for the transition of plastids into chloroplasts by coordinating nuclear and chloroplastic genomes under light conditions. Sigma factors are initiation factors that promote the attachment of plastid-encoded RNA polymerase (PEP) to specific initiation sites and are then released. Promotes the biosynthesis of plastid-encoded tRNAs (e.g. trnE-UUC and trnV- UAC) (572 aa)
