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

slsTitin; Key component in the assembly and functioning of adult and embryonic striated muscles and muscle tendons. By providing connections at the level of individual microfilaments, it contributes to the fine balance of forces between the two halves of the sarcomere. The size and extensibility of the cross-links are the main determinants of sarcomere extensibility properties of muscle. In non-muscle cells, seems to play a role in chromosome condensation and chromosome segregation during mitosis. Might link the lamina network to chromatin or nuclear actin, or both during interphase. (18468 aa)    
Predicted Functional Partners:
Mhc
Myosin heavy chain (Mhc) encodes the motor protein that provides the force for muscle contraction through its ATP-dependent interaction with actin filaments. It functions with essential and regulatory light chains.
   
 
 0.902
Zasp52
Z band alternatively spliced PDZ-motif protein 52 (Zasp52) encodes a member of the Zasp protein family. It is a scaffold protein that binds the product of Actn and localizes to muscle attachment sites and Z-discs in muscle cells, as well as localizing cortically in non-muscle cells. It plays a role in muscle development, especially in myofibril assembly.
   
 
 0.868
Act88F
Actin, indirect flight muscle; Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells. Required for proper formation of indirect flight muscle (IFM) myofibrils; Belongs to the actin family.
   
 
 0.860
bt
Bent, isoform F; Bent (bt) encodes the protein Projectin, a large protein associated with myosin thick filaments in insect muscles that contributes to the stiffness of flight muscle.
  
 
0.835
Actn
Alpha-actinin, sarcomeric; Alpha actinin (Actn) encodes an actin cross-linking protein with muscle and non-muscle specific isoforms, which are produced by alternative spicing. The muscle isoform has a role in muscle development while the non-muscle isoform localizes to ovarian ring canals and has a role in cytoskeletal remodeling of follicle cells; Belongs to the alpha-actinin family.
   
 
 0.834
Msp300
Muscle-specific protein 300 kDa (Msp300) encodes a Nesprin-like protein that is required for proper positioning of muscle nuclei, mitochondria, and neuromuscular junction.
   
 
 0.801
rols
Rolling pebbles (rols) encodes a protein required for myoblast fusion in founder cells. it interacts with the membrane spanning Immunoglobulin superfamily protein encoded by kirre and with the product of Mhcl.
   
 
 0.798
Mlp84B
Muscle LIM protein at 84B (Mlp84B) encodes a muscle cytoskeletal protein found primarily at the Z-line boundary. It maintains muscle structural integrity and regulates actin bundling.
   
 
 0.796
l(2)01289
Lethal (2) 01289, isoform F; It is involved in the biological process described with: cell redox homeostasis.
   
   0.763
wupA
Wings up A (wupA) encodes a cytoskeletal protein of the troponin complex of the muscle thin filament. It is involved in calcium-dependent regulation of muscle contraction, and in development of the embryonic heart, skeletal muscle and flight muscle It also contributes to non-muscle functions such as apico-basal polarity formation, nuclear division and maintenance of nuclear integrity.
