STRINGSTRING
KEX1 protein (Saccharomyces cerevisiae) - STRING interaction network
"KEX1" - Protease involved in the processing of killer toxin and alpha factor precursor 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

KEX1Protease involved in the processing of killer toxin and alpha factor precursor; cleaves Lys and Arg residues from the C-terminus of peptides and proteins; Protease with a carboxypeptidase B-like function involved in the C-terminal processing of the lysine and arginine residues from the precursors of K1, K2 and K28 killer toxins and a-factor (mating pheromone). Involved in the programmed cell death caused by defective N-glycosylation and contributes also to the active cell death program induced by acetic acid stress or during chronological aging. Promotes cell fusion by proteolytically [...] (729 aa)    
Predicted Functional Partners:
KEX2
Subtilisin-like protease (proprotein convertase), a calcium-dependent serine protease involved in the activation of proproteins of the secretory pathway; Processing of precursors of alpha-factors and killer toxin (814 aa)

CYR1
Adenylate cyclase, required for cAMP production and cAMP-dependent protein kinase signaling; the cAMP pathway controls a variety of cellular processes, including metabolism, cell cycle, stress response, stationary phase, and sporulation; Plays essential roles in regulation of cellular metabolism by catalyzing the synthesis of a second messenger, cAMP (2026 aa)
       
 
  0.948
PEP8
Vacuolar protein sorting protein that forms part of the multimeric membrane-associated retromer complex along with Vps35p, Vps29p, Vps17p, and Vps5p; essential for endosome-to-Golgi retrograde protein transport; Plays a role in vesicular protein sorting. Required for the endosome-to-Golgi retrieval of the vacuolar protein sorting receptor VPS10. Component of the membrane-associated retromer complex which is essential in endosome-to-Golgi retrograde transport. The VPS29-VPS26-VPS35 subcomplex may be involved in cargo selection (379 aa)

STE13
Dipeptidyl aminopeptidase, Golgi integral membrane protein that cleaves on the carboxyl side of repeating -X-Ala- sequences, required for maturation of alpha factor, transcription is induced by a-factor; Responsible for the proteolytic maturation of the alpha- factor precursor (931 aa)
           
  0.836
CHS3
Chitin synthase III, catalyzes the transfer of N-acetylglucosamine (GlcNAc) to chitin; required for synthesis of the majority of cell wall chitin, the chitin ring during bud emergence, and spore wall chitosan; Appears to be responsible for the synthesis of the majority of the chitin found in the cell wall periphery. It is involved in the synthesis of the chitin ring that forms in the cell wall just before bud emergence. This ring remains at the base of the bud as the bud grows and ultimately forms part of the bud scar marking the division site on the mother cell. Also catalyzes the syn [...] (1165 aa)

SHO1
Transmembrane osmosensor involved in activation of the Cdc42p- and MAP kinase-dependent filamentous growth pathway and the high-osmolarity glycerol response pathway; phosphorylated by Hog1p; interacts with Pbs2p, Msb2p, Hkr1p, and Ste11p; Plasma membrane osmosensor that activates the high osmolarity glycerol (HOG) MAPK signaling pathway in response to high osmolarity. Detects changes in external osmolarity and activates PBS2 through the stimulation of STE11 and targets PBS2 to the plasma membrane. PBS2 activation leads to changes in glycerol production that helps to balance the intrace [...] (367 aa)
       
      0.806
FLC2
Putative FAD transporter; required for uptake of FAD into endoplasmic reticulum; involved in cell wall maintenance; May be responsible for the transport of FAD into the endoplasmic reticulum lumen, where it is required for oxidative protein folding (783 aa)
