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

HpcaNeuron-specific calcium-binding protein hippocalcin; Calcium-binding protein that may play a role in the regulation of voltage-dependent calcium channels (By similarity). May also play a role in cyclic-nucleotide-mediated signaling through the regulation of adenylate and guanylate cyclases. (193 aa)    
Predicted Functional Partners:
Pi4kb
Phosphatidylinositol 4-kinase beta; Phosphorylates phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol- 1,4,5,-trisphosphate (PIP). May regulate Golgi disintegration/reorganization during mitosis, possibly via its phosphorylation. Involved in Golgi-to-plasma membrane trafficking. Belongs to the PI3/PI4-kinase family. Type III PI4K subfamily.

Calb2
Calretinin; Calretinin is a calcium-binding protein which is abundant in auditory neurons.
   
 
 0.650
Pvalb
Parvalbumin alpha; In muscle, parvalbumin is thought to be involved in relaxation after contraction. It binds two calcium ions; Belongs to the parvalbumin family.
   
 
 0.623
Guf1
Translation factor GUF1, mitochondrial; Promotes mitochondrial protein synthesis. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Binds to mitochondrial ribosomes in a GTP-dependent manner.
      
 0.615
Gucy2d
Guanylate cyclase 2D; Functions as an olfactory receptor activated by a urine odorant, uroguanylin. Activated as well by the volatile semiochemicals carbon disulfide (CS2) and carbon dioxide (CO2) (By similarity). Has guanylate cyclase activity upon binding of the ligand. Activation of GUCY2D neurons leads to the cGMP-dependent activation of the CNGA3 channels, membrane depolarization and an increase in action potential frequency. Signaling pathways activated by GUCY2D may trigger social behaviors such as acquisition of food preference (By similarity).
   
 
 0.600
Ap2b1
AP-2 complex subunit beta; Component of the adaptor protein complex 2 (AP-2). Adaptor protein complexes function in protein transport via transport vesicles in different membrane traffic pathways. Adaptor protein complexes are vesicle coat components and appear to be involved in cargo selection and vesicle formation. AP-2 is involved in clathrin-dependent endocytosis in which cargo proteins are incorporated into vesicles surrounded by clathrin (clathrin-coated vesicles, CCVs) which are destined for fusion with the early endosome. The clathrin lattice serves as a mechanical scaffold but [...]
      
 0.588
Calb1
Calbindin; Buffers cytosolic calcium. May stimulate a membrane Ca(2+)- ATPase and a 3',5'-cyclic nucleotide phosphodiesterase.
   
 
 0.535
Calml3
Calmodulin-like protein 3; May function as a specific light chain of unconventional myosin-10 (MYO10), also enhances MYO10 translation, possibly by acting as a chaperone for the emerging MYO10 heavy chain protein. May compete with calmodulin by binding, with different affinities, to cellular substrates (By similarity).
    
 
 0.511
Kcnd3
Potassium voltage-gated channel subfamily D member 3; Pore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to I(To) current in heart and I(Sa) current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits. Belongs to the potassium channel family. D (Shal) (TC 1.A.1.2) subfamily. Kv4.3/KCND3 sub-subfamily.
   
 
 0.505
Snap25
Synaptosomal-associated protein; Belongs to the SNAP-25 family.
