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.

azo2279
Conserved hypothetical protein. Homology to Avin02000067 of Azotobacter vinelandii of 50% (gi|23105742|ref|ZP_00092196.1|(NBCI ENTREZ)). InterPro: Ankyrin-repeat. The ankyrin repeat is one of the most common protein-protein interaction motifs in nature. Ankyrin repeats are tandemly repeated modules of about 33 amino acids.The ankyrin fold appears to be defined by its structure rather than its function since there is no specific sequence or structure which is universally recognised by it. The conserved fold of the ankyrin repeat unit is known from several crystal and solution structures [...]

ank1
Putative ankyrin repeat harbouring exported protein; Hypothetical protein KIAA1223 (Fragment). TREMBL:Q8XYH0:35% identity; TREMBL:Q7VXC9:35% The ankyrin repeat is one of the most common protein-protein interaction motifs in nature. Ankyrin repeats are tandemly repeated modules of about 33 amino acids. They occur in a large number of functionally diverse proteins mainly from eukaryotes.Each Ankyrin repeat folds into a helix-loop-helix structure with a beta-hairpin/loop region projecting out from the helices at a 90 angle. The repeats stack together to form an L-shaped structure InterPro [...]

tnkS
Putative tankyrase type protein; Tankyrase 2 (EC 2.4.2.30) (TANK2) (Tankyrase II) (TNKS-2) (TRF1- interacting ankyrin-related ADP-ribose polymerase 2) (Tankyrase-like protein) (Tankyrase-related protein). May regulate vesicle trafficking and modulate the subcellular distribution of SLC2A4/GLUT4-vesicles. Has PARP activity and can modify TRF1 and thereby contribute to the regulation of telomere length. TREMBL:Q800E0:34%; Q8YTG9:36% identity. InterPro: Ankyrin-repeat Mop: molybdenum-pterin binding domain Presence of signal peptide (SignalP) but absence of transmembrane helices; Function [...]
