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:
a 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 to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology
Your Input:
PI4KB2Phosphatidylinositol 4-kinase beta 2; Acts on phosphatidylinositol (PtdIns) in the first committed step in the production of the second messenger inositol-1,4,5- trisphosphate (By similarity). Necessary for proper organization of the trans-Golgi network (TGN) and post-Golgi secretion in root hairs. Together with PI4KB1, required during polarized root hair expansion and pollen tube elongation. Functions redundantly with PI4KB1 upstream of the cold response phosphoinositide-dependent phospholipase C (PI-PLC) pathway. (1116 aa)
ARC5Dynamin-like protein ARC5; Probable GTPase component of both plastid and peroxisme division machinery. Required for the last steps of plastid division specifically in mesophyll-cell, when the narrow isthmus breaks, facilitating the separation of the daughter plastids. Necessary for peroxisome activities. Seems to influence stromule (stroma-filled tubular extensions of the plastid envelope membrane) length and frequency. Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. (777 aa)
PDV1Plastid division protein PDV1; Component of the plastid division machinery. Required to mediate the recruitment of ARC5 at the midplastid constriction site in the cytoplasm. (272 aa)
PI4KB1Phosphatidylinositol 4-kinase beta 1; Acts on phosphatidylinositol (PtdIns) in the first committed step in the production of the second messenger inositol-1,4,5- trisphosphate. Necessary for proper organization of the trans-Golgi network (TGN) and post-Golgi secretion in root hairs. Together with PI4KB2, required during polarized root hair expansion and pollen tube elongation. Functions redundantly with PI4KB2 upstream of the cold response phosphoinositide-dependent phospholipase C (PI-PLC) pathway. (1121 aa)
PI4KA1Phosphatidylinositol 4-kinase alpha 1; Acts on phosphatidylinositol (PtdIns) in the first committed step in the production of the second messenger inositol-1,4,5,- trisphosphate. Can bind to phosphatidylinositol 4-monophosphate (PI-4-P or PtdIns4P), phosphatidylinositol 4,5-bisphosphate (PI-4,5-P2 or PtdIns4,5P2), and phosphatidic acid (PtdOH), but not to 3- phosphoinositides. May function upstream of the cold response phosphoinositide-dependent phospholipase C (PI-PLC) pathway. (2028 aa)
PDV2Plastid division protein PDV2; Component of the plastid division machinery. Required to mediate the recruitment of ARC5 at the midplastid constriction site in the cytoplasm. Relays plastid division site position between stroma and outer surface via interactions with the cytoplasmic ARC5 and the inner membrane ARC6 that recruits stromal FtsZ ring. (307 aa)
