F3F20.6 protein (Arabidopsis thaliana) - STRING interaction network
"F3F20.6" - Inactive glucose-1-phosphate adenylyltransferase small subunit 2, chloroplastic 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
Your Input:
Gene Fusion
F3F20.6Inactive glucose-1-phosphate adenylyltransferase small subunit 2, chloroplastic; Encodes the small subunit of ADP-glucose pyrophosphorylase. The small subunit is the catalytic isoform responsible for ADP-glucose pyrophosphorylase activity. The presence of the small subunit is required for large subunit stability. Two isoforms of the small subunit (ApS1 and ApS2) have been described. ApS2 is a minor small subunit isoform present in all plant tissues tested; Belongs to the bacterial/plant glucose-1-phosphate adenylyltransferase family (476 aa)    
Predicted Functional Partners:
Granule-bound starch synthase 1, chloroplastic/amyloplastic; Required for the synthesis of amylose. Destroyed as it is released from the starch granules during the night. The circadian expression is controlled by CCA1 and LHY transcription factors (610 aa)
UTP--glucose-1-phosphate uridylyltransferase 2; Converts glucose 1-phosphate to UDP-glucose, which is the major glycosyl donor for polysaccharides. Acts redundantly with UGP1 and is essential for the synthesis of sucrose, starch and cell wall, and callose deposition; Belongs to the UDPGP type 1 family (469 aa)
Encodes a sucrose synthase (SUS2). The activity of the enzyme could not be assayed as proved to be insoluble (PMID 17257168). However, analyses of an sus2 mutant revealed a deficiency in sucrose synthase activity 12 and 15 days after flowering. There are some reports that SUS2 transcript levels are increased in leaves specifically by O(2) deficiency whereas other reports indicate that SUS2 is expressed only in seeds. Immulocalization shows that SUS2 is present in the cytosol of developing seeds, but, it also associated with plastids, though not located within them (807 aa)
Phosphoglucomutase, chloroplastic; Encodes a plastid isoform of the enzyme phosphoglucomutase involved in controlling photosynthetic carbon flow. Effective petiole movement against the direction of the gravity requires functional PGM activity that is required for full development of amyloplasts (623 aa)
Starch synthase 1, chloroplastic/amyloplastic; SSI is a plastidial enzyme and crucial for the synthesis of normal amylopectin in the leaves of Arabidopsis. The absence of SSI results in a deficiency in the number of shorter glucans which in turn affect the formation and connection of the amylopectin clusters in starch (652 aa)
Starch synthase 2, chloroplastic/amyloplastic; Involved in the synthesis of glycan chains within amylopectin in leaves. Is required to produce chains with a degree of polymerization of 12 to 25 (DP12-DP25); Belongs to the glycosyltransferase 1 family. Bacterial/plant glycogen synthase subfamily (792 aa)
Glycosyl transferase, family 35; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (By similarity). May be not required for the degradation of starch, but the phosphorolysis of starch may play an important role in water stress tolerance (962 aa)
Alpha-glucan phosphorylase 2, cytosolic; Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties (By similarity) (841 aa)
Sucrose synthase 5; Sucrose-cleaving enzyme that provides UDP-glucose and fructose for various metabolic pathways. Functions in callose synthesis at the site of phloem sieve elements (836 aa)
ADP-glucose pyrophosphorylase family protein; Its function is described as transferase activity, nucleotidyltransferase activity; Involved in response to cadmium ion, biosynthetic process; Located in peroxisome; Expressed in 24 plant structures; Expressed during 13 growth stages; Contains the following InterPro domains- Trimeric LpxA-like (InterPro-IPR011004), Nucleotidyl transferase (InterPro-IPR005835); BEST Arabidopsis thaliana protein match is- ADP-glucose pyrophosphorylase family protein (TAIR-AT2G04650.1); Has 8966 Blast hits to 8959 proteins in 2015 species- Archae - 647; Bacter [...] (415 aa)
