STRINGSTRING
STRING protein interaction network
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

scaA
Sca1 complex scaffold protein scaA; Component of the Sca1 complex, a regulator of cell motility, chemotaxis and signal relay. The Sca1 complex is recruited to the plasma membrane in a chemoattractant- and F-actin- dependent manner and is enriched at the leading edge of chemotaxing cells where it regulates F-actin dynamics and signal relay by controlling the activation of rasC and the downstream target of rapamycin complex 2 (TORC2)-Akt/protein kinase B (PKB) pathway. ScaA acts as a molecular scaffold, bringing together gefA, gefH and phr with PP2A.

gflB
Ras guanine nucleotide exchange factor glfB; GpaB-activated, rapA-specific guanine nucleotide exchange factor, involved in the regulation of the balance between Ras and Rap signaling at the leading edge of chemotaxing cells. Spatially localized activation of Rap and Ras induces F-actin polymerization at the leading edge of chemotaxing cells through the Rac, PI3K, and TORC2 pathways. Acts also as a key regulator of actin-driven membrane protrusions during processes such as phagocytosis and cytokinesis, possibly by modulating rapA signaling pathways.
