STRINGSTRING
PEA2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PEA2" - Coiled-coil polarisome protein required for polarized morphogenesis, cell fusion, and low affinity Ca2+ influx in Saccharomyces cerevisiae
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

PEA2Coiled-coil polarisome protein required for polarized morphogenesis, cell fusion, and low affinity Ca2+ influx; forms polarisome complex with Bni1p, Bud6p, and Spa2p; localizes to sites of polarized growth; Localized to sites of polarized growth and is required for efficient mating and bipolar budding (420 aa)    
Predicted Functional Partners:
SPA2
Component of the polarisome, which functions in actin cytoskeletal organization during polarized growth; acts as a scaffold for Mkk1p and Mpk1p cell wall integrity signaling components; potential Cdc28p substrate; Involved in pheromone-induced morphogenesis and efficient mating, perhaps as a cytoskeletal protein (1466 aa)
       
  0.999
BUD6
Actin- and formin-interacting protein; stimulates actin cable nucleation by recruiting actin monomers to Bni1p; involved in polarized cell growth; isolated as bipolar budding mutant; potential Cdc28p substrate; Not essential for mitotic growth but is necessary for normal morphogenesis. Involved in the organization and/or function of the actin cytoskeleton (788 aa)
       
  0.995
BNI1
Formin, nucleates the formation of linear actin filaments, involved in cell processes such as budding and mitotic spindle orientation which require the formation of polarized actin cables, functionally redundant with BNR1; Required for the assembly of F-actin structures, such as actin cables and stress fibers. Nucleates actin filaments. Binds to the barbed end of the actin filament and acts as leaky capper, slowing both polymerization and depolymerization. Protects the growing actin fiber from tight capping proteins and so increases the time of elongation and the total amount of F-acti [...] (1953 aa)
         
  0.988
MSB3
GTPase-activating protein for Sec4p and several other Rab GTPases, regulates exocytosis via its action on Sec4p, also required for proper actin organization; similar to Msb4p; both Msb3p and Msb4p localize to sites of polarized growth; Regulates exocytosis by functioning as a GAP for SEC4. Stimulates specifically the GTPase activity of YPT6. Also required for efficient polarization of the actin patches (633 aa)
       
  0.954
MSB4
GTPase-activating protein of the Ras superfamily that acts primarily on Sec4p, localizes to the bud site and bud tip, has similarity to Msb3p; msb3 msb4 double mutation causes defects in secretion and actin organization; Regulates exocytosis by functioning as a GAP for SEC4. Also required for efficient polarization of the actin patches (492 aa)
       
  0.937
GIC2
Redundant rho-like GTPase Cdc42p effector; homolog of Gic1p; involved in initiation of budding and cellular polarization; interacts with Cdc42p via the Cdc42/Rac-interactive binding (CRIB) domain and with PI(4,5)P2 via a polybasic region; Required for cell size and shape control, bud site selection, bud emergence, actin cytoskeletal organization, mitotic spindle orientation/positioning, and mating projection formation in response to mating pheromone (383 aa)
       
 
  0.844
BEM2
Rho GTPase activating protein (RhoGAP) involved in the control of cytoskeleton organization and cellular morphogenesis; required for bud emergence; GTPase-activating protein (GAP) for RHO1 and RHO2. Involved in the control of cellular morphogenesis. Required for proper bud site selection and bud emergence (2167 aa)
       
 
  0.813
FUS2
Cytoplasmic protein localized to the shmoo tip; required for the alignment of parental nuclei before nuclear fusion during mating; Promotes cell fusion during zygote formation (677 aa)
       
 
  0.780
CDC42
Small rho-like GTPase, essential for establishment and maintenance of cell polarity; mutants have defects in the organization of actin and septins; Involved in development of cell polarity during the cell division cycle, and essential for bud emergence. Affects signaling in the pheromone-response pathway through the STE20 protein kinase. Negatively regulated by the GTPase-activating proteins RGA1, BEM3, and BEM4 (191 aa)
       
 
  0.779
BNR1
Formin, nucleates the formation of linear actin filaments, involved in cell processes such as budding and mitotic spindle orientation which require the formation of polarized actin cables, functionally redundant with BNI1; May organize microtubules by mediating spindle positioning and movement in the budding process. Potential target of the RHO family members (By similarity) (1375 aa)
