SR45 protein (Arabidopsis thaliana) - STRING interaction network
"SR45" - Encodes SR45, a member of the highly conserved family of serine/arginine-rich in Arabidopsis thaliana
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

SR45Encodes SR45, a member of the highly conserved family of serine/arginine-rich (SR) proteins, which play key roles in pre-mRNA splicing and other aspects of RNA metabolism. SR45 is a spliceosome protein, interacts with SR33 and the U1-70K protein of the U1 snRNP. Also involved in plant sugar response. sr45-1 mutation confers hypersensitivity to glucose during early seedling growth (425 aa)    
Predicted Functional Partners:
RNA-binding (RRM/RBD/RNP motifs) family protein; General splicing factor. Can promote splice site selection in vitro presumably by antagonizing the effects of the A1 heterogeneous nuclear ribonucleoprotein. May have an essential function during early plant development; Belongs to the splicing factor SR family. SR subfamily (303 aa)
Splicing factor, putative; Its function is described as binding; Involved in mRNA processing; Located in chloroplast; Expressed in 26 plant structures; Expressed during 15 growth stages; Contains the following InterPro domains- HEAT (InterPro-IPR000357), Armadillo-like helical (InterPro-IPR011989), Splicing factor 3B subunit 1 (InterPro-IPR015016), HEAT, type 2 (InterPro-IPR021133), Armadillo-type fold (InterPro-IPR016024); Has 1807 Blast hits to 1807 proteins in 277 species- Archae - 0; Bacteria - 0; Metazoa - 736; Fungi - 347; Plants - 385; Viruses - 0; Other Eukaryotes - 339 (source [...] (1269 aa)
U1 small nuclear ribonucleoprotein 70 kDa; Mediates the splicing of pre-mRNA by binding to the loop I region of U1-snRNA (427 aa)
SNW/SKI-interacting protein; Splicing factor involved in post-transcriptional regulation of circadian clock and flowering time genes. Associates with the pre-mRNA of PRR7, PRR9, ELF3 and GI, and is necessary for the regulation of their alternative splicing and mRNA maturation. Probably involved in splice site recognition; Belongs to the SNW family (613 aa)
Serine/arginine-rich splicing factor SR30; Regulatory splicing factor that modulates alternative splicing and gene expression in specific cell types. Autoregulates its own expression. Probably involved in intron recognition and spliceosome assembly; Belongs to the splicing factor SR family. SR subfamily (268 aa)
Serine/arginine-rich splicing factor RSZ21; Encodes a 9G8-like serine-arginine rich (SR) protein that interacts in vivo with U1-70K, a U1 small nuclear ribonucleoprotein 70-kDa protein that is involved in nuclear precursor mRNA processing (187 aa)
RNA-binding (RRM/RBD/RNP motifs) family protein; Probably involved in intron recognition and spliceosome assembly (278 aa)
Serine/arginine-rich splicing factor SR34A; Probably involved in intron recognition and spliceosome assembly (300 aa)
Zinc finger C-x8-C-x5-C-x3-H type family protein; U2 auxiliary factor small subunit. The atU2AF35b protein and its homolog, atU2AF35a, contain most of the conserved domains of hsU2AF35, including the psiRRM, one RS domain, two zinc fingers, and the two regions for interacting with U2AF large subunit. Both proteins lack the stretch of glycines present in human U2AF35. The sequences are overall 83% identical, and each Arabidopsis homolog shows approximately 70% similarity to hsU2AF35. U2AF(35) homologs were also identified from maize, rice and other plants with large-scale EST project [...] (283 aa)
Transducin/WD40 repeat-like superfamily protein; Contains the following InterPro domains- WD40 repeat 2 (InterPro-IPR019782), WD40 repeat, conserved site (InterPro-IPR019775), WD40 repeat (InterPro-IPR001680), G-protein beta WD-40 repeat, region (InterPro-IPR020472), WD40 repeat-like-containing domain (InterPro-IPR011046), WD40-repeat-containing domain (InterPro-IPR017986), WD40/YVTN repeat-like-containing domain (InterPro-IPR015943), WD40 repeat, subgroup (InterPro-IPR019781); BEST Arabidopsis thaliana protein match is- Transducin/WD40 repeat-like superfamily protein (TAIR-AT3G49660.1 [...] (343 aa)
