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

SAP4Candidapepsin-4; Secreted aspartic peptidases (SAPs) are a group of ten acidic hydrolases considered as key virulence factors. These enzymes supply the fungus with nutrient amino acids as well as are able to degrade the selected host's proteins involved in the immune defense. Activates host systemic immunity. During infection, plays an important role in penetration into deeper tissues and interaction with host defense. Moreover, acts toward human hemoglobin though limited proteolysis to generate a variety of antimicrobial hemocidins, enabling to compete with the other microorganisms of [...] (417 aa)    
Predicted Functional Partners:
HWP1
Hyphal wall protein 1; Major hyphal cell wall protein which plays a role of adhesin and is required for mating, normal hyphal development, cell-to-cell adhesive functions necessary for biofilm integrity, attachment to host, and virulence. Promotes interactions with host and bacterial molecules, thus leading to effective colonization within polymicrobial communities. Plays a crucial role in gastrointestinal colonization, in mucosal symptomatic and asymptomatic infections, in vaginitis, as well as in lethal oroesophageal candidiasis, caused by the combined action of fungal virulence fact [...]

ALS3
Agglutinin-like protein 3; Cell surface adhesion protein which mediates both yeast-to- host tissue adherence and yeast aggregation. Plays an important role in the biofilm formation and pathogenesis of C.albicans infections. Necessary for C.albicans to bind to N-cadherin on endothelial cells and E-cadherin on oral epithelial cells and subsequent endocytosis by these cells. During disseminated infection, mediates initial trafficking to the brain and renal cortex and contributes to fungal persistence in the kidneys. Belongs to the ALS family.

SAP5
Candidapepsin-5; Secreted aspartic peptidases (SAPs) are a group of ten acidic hydrolases considered as key virulence factors. These enzymes supply the fungus with nutrient amino acids as well as are able to degrade the selected host's proteins involved in the immune defense. During infection, plays an important role in penetration into deeper tissues and interaction with host defense. Moreover, acts toward human hemoglobin though limited proteolysis to generate a variety of antimicrobial hemocidins, enabling to compete with the other microorganisms of the same physiological niche usin [...]

HYR1
Hyphally regulated cell wall protein 1; GPI-anchored hyphal cell wall protein required for hyphal growth and virulence. Involved in innate immune cell evasion through confering resistance to neutrophil killing. Binds kininogen, the proteinaceous kinin precursor, and contributes to trigger the kinin- forming cascade on the cell surface. Production of kinins is often involved in the human host defense against microbial infections. Belongs to the HYR1/IFF family.

ECE1
Extent of cell elongation protein 1; Secreted protein involved in biofilm formation. Further cleaved by KEX2 in 8 similar peptides (ECE1- I to ECE1-VIII).
   
  
 0.696
ALS1
Agglutinin-like protein 1; Major cell surface adhesion protein which mediates both yeast-to-host tissue adherence and yeast aggregation. Acts as a downstream effector of the EFG1 regulatory pathway. Required for rapamycin-induced aggregation of C.albicans. Binds glycans and mediates adherence to endothelial and epithelial cells, thereby playing an important role in the pathogenesis of C.albicans infections.

PLB2
Lysophospholipase.

EFG1
Enhanced filamentous growth protein 1; Transcriptional regulator of the switch between 2 heritable states, the white and opaque states. These 2 cell types differ in many characteristics, including cell structure, mating competence, and virulence. Each state is heritable for many generations, and switching between states occurs stochastically, at low frequency. Antagonizes the action of WOR1, WOR2 and CZF1, and promotes the white state. In white cells, EFG1 represses WOR1 indirectly through WOR2 to maintain white cell identity. Binds target gene promoters at the EFG1 recognition sequenc [...]

CPH1
Transcription factor CPH1; Transcription factor involved in the formation of pseudohyphae and hyphae. It is likely to play a role in the developmental switch between yeast and mycelial forms. May be involved in a signal transduction system, strengthening the possibility of a sexual phase up to now undetected, and similar to that of the yeast mating pathway.

SOD5
Cell surface Cu-only superoxide dismutase 5; Superoxide dismutases serve to convert damaging superoxide radicals, a key form of ROS, to less damaging hydrogen peroxide that can be converted into water by catalase action. Degrades host-derived reactive oxygen species to escape innate immune surveillance. Involved in the occurrence of miconazole-tolerant persisters in biofilms. Persisters are cells that survive high doses of an antimicrobial agent. The unusual attributes of SOD5-like fungal proteins, including the absence of zinc and an open active site that readily captures extracellula [...]
