Thioredoxin_2

Thioredoxin_2
PFAM accession number:PF13098
Interpro abstract (IPR012336):

Several biological processes regulate the activity of target proteins through changes in the redox state of thiol groups (S2 to SH2), where a hydrogen donor is linked to an intermediary disulphide protein. Such processes include the ferredoxin/thioredoxin system, the NADP/thioredoxin system, and the glutathione/glutaredoxin system [ (PUBMED:15862094) ]. Several of these disulphide proteins share a common structure, consisting of a three-layer alpha/beta/alpha core.
