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
Your Input:
dckDeoxyadenosine/deoxycytidine kinase; Plays an essential role in generating the deoxyribonucleotide precursors dATP AND dCTP for DNA metabolism. The phosphate acceptor specificity is strict toward deoxyadenosine (dAdo) and deoxycytidine (dCyd). The specificity toward the sugar moiety of the nucleoside is less strict. Both 2-deoxyribose, ribose, and arabinose nucleosides are phosphorylated, although the 2-deoxyribonucleosides are preferred. The phosphate donor specificity is dependent on the deoxyribonucleoside substrate, but GTP is efficient with both deoxycytidine and deoxyadenosine. O [...] (217 aa)
