STRINGSTRING
VCX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"VCX1" - Vacuolar membrane antiporter with Ca2+/H+ and K+/H+ exchange activity, involved in control of cytosolic Ca2+ and K+ concentrations 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

VCX1Vacuolar membrane antiporter with Ca2+/H+ and K+/H+ exchange activity, involved in control of cytosolic Ca2+ and K+ concentrations; has similarity to sodium/calcium exchangers, including the bovine Na+/Ca2+,K+ antiporter; Has a role in promoting intracellular calcium ion sequestration via the exchange of calcium ions for hydrogen ions across the vacuolar membrane. Involved also in manganese ion homeostasis via its uptake into the vacuole (411 aa)    
Predicted Functional Partners:
PMC1
Vacuolar Ca2+ ATPase involved in depleting cytosol of Ca2+ ions; prevents growth inhibition by activation of calcineurin in the presence of elevated concentrations of calcium; similar to mammalian PMCA1a; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Transports the calcium to the vacuole and participates in the control of the cytosolic free calcium (1173 aa)

PMR1
High affinity Ca2+/Mn2+ P-type ATPase required for Ca2+ and Mn2+ transport into Golgi; involved in Ca2+ dependent protein sorting and processing; mutations in human homolog ATP2C1 cause acantholytic skin condition Hailey-Hailey disease; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium. Has a role in the secretory pathway (950 aa)
       
 
  0.917
CNB1
Calcineurin B; the regulatory subunit of calcineurin, a Ca++/calmodulin-regulated type 2B protein phosphatase which regulates Crz1p (a stress-response transcription factor), the other calcineurin subunit is encoded by CNA1 and/or CMP1; Regulatory subunit of calcineurin, a calcium-dependent, calmodulin stimulated protein phosphatase. Confers calcium sensitivity (175 aa)
       
 
  0.904
ENA1
P-type ATPase sodium pump, involved in Na+ and Li+ efflux to allow salt tolerance; This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of the sodium or lithium ions to allow salt tolerance. Is negatively modulated by SIS2/HAL3 (1091 aa)
       
 
  0.898
CNA1
Calcineurin A; one isoform (the other is CMP2) of the catalytic subunit of calcineurin, a Ca++/calmodulin-regulated protein phosphatase which regulates Crz1p (a stress-response transcription factor), the other calcineurin subunit is CNB1; Calcium-dependent, calmodulin-stimulated protein phosphatase. This subunit may have a role in the calmodulin activation of calcineurin (553 aa)

NHX1
Na+/H+ and K+/H+ exchanger, required for intracellular sequestration of Na+ and K+; located in the vacuole and late endosome compartments; required for osmotolerance to acute hypertonic shock and for vacuolar fusion; Endosomal/prevacuolar electroneutral Na(+)/H(+) exchanger which mediates intracellular sequestration of Na(+) cations, regulates vacuolar pH and contributes to osmotolerance following sudden exposure to hyperosmotic media. Contributes also to the postdiauxic/stationary phase resistance to osmotic stress and allows for the continued growth of cells until the acquired osmoto [...] (633 aa)

MID1
N-glycosylated integral membrane protein of the ER and plasma membrane; functions as a stretch-activated Ca2+-permeable cation channel required for Ca2+ influx stimulated by pheromone; interacts with Cch1p; forms an oligomer; Calcium-permeable, cation-selective stretch-activated channel (SAC). Required for calcium influx and for vitality of MATa cells in a late, pheromone-induced event of the mating process requiring calcium induced signaling.

CCH1
Voltage-gated high-affinity calcium channel involved in calcium influx in response to some environmental stresses as well as exposure to mating pheromones; interacts and co-localizes with Mid1p, suggesting Cch1p and Mid1p function together; Voltage-gated, high-affinity calcium channel involved in calcium influx in response to some environmental stresses as well as exposure to mating pheromones.
