STRINGSTRING
CAB2 protein (Saccharomyces cerevisiae) - STRING interaction network
"CAB2" - Probable phosphopantothenoylcysteine synthetase 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

CAB2Probable phosphopantothenoylcysteine synthetase (PPCS), which catalyzes the second step of coenzyme A biosynthesis from pantothenate; null mutant lethality is complemented by E. coli coaBC (encoding a bifunctional enzyme with PPCS activity); Catalyzes the first step in the biosynthesis of coenzyme A from vitamin B5, where cysteine is conjugated to 4’- phosphopantothenate to form 4-phosphopantothenoylcysteine (365 aa)    
Predicted Functional Partners:
CAB4
Probable pantetheine-phosphate adenylyltransferase (PPAT), which catalyzes the fourth step in the biosynthesis of coenzyme A from pantothenate; null mutant lethality is complemented by E. coli coaD (encoding PPAT); widely conserved; Reversibly transfers an adenylyl group from ATP to 4’- phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate (By similarity). Plays a role in the physiological regulation of the intracellular CoA concentration (305 aa)
     
  0.998
CAB3
Subunit of a phosphopantothenoylcysteine decarboxylase (PPCDC; Cab3p, Sis2p, Vhs3p) complex, which catalyzes the third step of coenzyme A biosynthesis; null mutant lethality is complemented by E. coli coaBC; Component of the phosphopantothenoylcysteine decarboxylase (PPCDC) involved in the coenzyme A synthesis (571 aa)
       
  0.992
CAB1
Pantothenate kinase, ATP-D-pantothenate 4’-phosphotransferase; catalyzes the first committed step in the universal biosynthetic pathway for synthesis of coenzyme A (CoA); transcriptionally regulated by Upc2p via a sterol response element; Plays a role in the physiological regulation of the intracellular CoA concentration (367 aa)
     
 
  0.985
CAB5
Probable dephospho-CoA kinase (DPCK) that catalyzes the last step in coenzyme A biosynthesis; null mutant lethality is complemented by E. coli coaE (encoding DPCK); detected in purified mitochondria in high-throughput studies; Catalyzes the phosphorylation of the 3’-hydroxyl group of dephosphocoenzyme A to form coenzyme A (241 aa)
   
  0.979
SIS2
Negative regulatory subunit of protein phosphatase 1 Ppz1p and also a subunit of the phosphopantothenoylcysteine decarboxylase (PPCDC; Cab3p, Sis2p, Vhs3p) complex, which catalyzes the third step of coenzyme A biosynthesis; Component of the phosphopantothenoylcysteine decarboxylase (PPCDC) involved in the coenzyme A synthesis. Acts as an inhibitory subunit of protein phosphatase PPZ1, which is involved in many cellular processes such as G1-S transition or salt tolerance. Also modulates the expression of the ENA1 ATPase (562 aa)
         
  0.966
VHS3
Negative regulatory subunit of protein phosphatase 1 Ppz1p and also a subunit of the phosphopantothenoylcysteine decarboxylase (PPCDC; Cab3p, Sis2p, Vhs3p) complex, which catalyzes the third step of coenzyme A biosynthesis; Component of the phosphopantothenoylcysteine decarboxylase (PPCDC) involved in the coenzyme A synthesis. Acts as an inhibitory subunit of protein phosphatase PPZ1, which is involved in many cellular processes such as G1-S transition or salt tolerance (674 aa)
