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

Score
MepeMatrix extracellular phosphoglycoprotein; Regulates renal phosphate and uric acid excretion. Regulates bone mineralization by osteoblasts and cartilage mineralization by chondrocytes. Regulates the mineralization of the extracellular matrix of the craniofacial complex, such as teeth, bone and cartilage. Increases dental pulp stem cell proliferation (By similarity). Belongs to the PF07175/osteoregulin family. (441 aa)    
Predicted Functional Partners:
Dmp1
Dentin matrix acidic phosphoprotein 1; May have a dual function during osteoblast differentiation. In the nucleus of undifferentiated osteoblasts, unphosphorylated form acts as a transcriptional component for activation of osteoblast- specific genes like osteocalcin. During the osteoblast to osteocyte transition phase it is phosphorylated and exported into the extracellular matrix, where it regulates nucleation of hydroxyapatite (By similarity).

Phex
Phosphate-regulating neutral endopeptidase PHEX; Peptidase that cleaves SIBLING (small integrin-binding ligand, N-linked glycoprotein)-derived ASARM peptides, thus regulating their biological activity (By similarity). Cleaves ASARM peptides between Ser and Glu or Asp residues (By similarity). Regulates osteogenic cell differentiation and bone mineralization through the cleavage of the MEPE-derived ASARM peptide. Promotes dentin mineralization and renal phosphate reabsorption by cleaving DMP1- and MEPE-derived ASARM peptides. Inhibits the cleavage of MEPE by CTSB/cathepsin B thus preven [...]
   
 
 0.883
Ibsp
Bone sialoprotein 2; Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction. Promotes Arg-Gly-Asp-dependent cell attachment (By similarity).
   
  
 0.801
Fgf23
Fibroblast growth factor 23; Regulator of phosphate homeostasis (By similarity). Inhibits renal tubular phosphate transport by reducing SLC34A1 levels (By similarity). Acts directly on the parathyroid to decrease PTH secretion (By similarity). Regulator of vitamin-D metabolism (By similarity). Negatively regulates osteoblasts differentiation and matrix mineralization (By similarity). Upregulates EGR1 expression in the presence of KL; Belongs to the heparin-binding growth factors family.
   
  
 0.799
Spp1
Osteopontin; Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction; Belongs to the osteopontin family.
      
 0.797
Sost
Sclerostin; Negative regulator of bone growth that acts through inhibition of Wnt signaling and bone formation; Belongs to the sclerostin family.
   
  
 0.783
Sfrp4
Secreted frizzled-related sequence protein 4; Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through direct interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP4 plays a role in bone morphogenesis. May also act as a regulator of adult uterine morphology and function. May also increase apoptosis during ovulation possibly through modulation of FZ1/FZ4/WNT4 signaling (By similarity). Has phosphaturic effects by specifically inhibiting sodium-dependent phosphate uptake (By similarity).
      
 0.769
Enam
Enamelin; Involved in the mineralization and structural organization of enamel. Involved in the extension of enamel during the secretory stage of dental enamel formation.
   
  
 0.765
Pth
Parathyroid hormone; PTH elevates calcium level by dissolving the salts in bone and preventing their renal excretion; Belongs to the parathyroid hormone family.
   
  
 0.732
Amtn
Amelotin; Is a promoter of calcium phosphate mineralization, playing a critical role in the formation of the compact, mineralized, aprismatic enamel surface layer during the maturation stage of amelogenesis. Belongs to the amelotin family.
