Protein Disulfide Oxidoreductases and Other Proteins with a Thioredoxin fold; The thioredoxin (TRX)-like superfamily is a large, diverse group of proteins containing a TRX fold. Many members contain a classic TRX domain with a redox active CXXC motif. They function as protein disulfide oxidoreductases (PDOs), altering the redox state of target proteins via the reversible oxidation of their active site dithiol. The PDO members of this superfamily include the families of TRX, protein disulfide isomerase (PDI), tlpA, glutaredoxin, NrdH redoxin, and bacterial Dsb proteins (DsbA, DsbC, DsbG, DsbE, DsbDgamma). Members of the superfamily that do not function as PDOs but contain a TRX-fold domain include phosducins, peroxiredoxins, glutathione (GSH) peroxidases, SCO proteins, GSH transferases (GST, N-terminal domain), arsenic reductases, TRX-like ferredoxins and calsequestrin, among others.

Dim1 family, Dim1-like protein (DLP) subfamily; DLP is a novel protein which shares 38% sequence identity to Dim1. Like Dim1, it is also implicated in pre-mRNA splicing and cell cycle progression. DLP is located in the nucleus and has been shown to interact with the U5 small nuclear ribonucleoprotein particle (snRNP)-specific 102kD protein (or Prp6). Dim1 protein, also known as U5 snRNP-specific 15kD protein is a component of U5 snRNP, which pre-assembles with U4/U6 snRNPs to form a [U4/U6:U5] tri-snRNP complex required for pre-mRNA splicing. Dim1 adopts a thioredoxin fold but does not contain the redox active CXXC motif.

 10-96 7.19e-48

Dim1 family; Dim1 is also referred to as U5 small nuclear ribonucleoprotein particle (snRNP)-specific 15kD protein. It is a component of U5 snRNP, which pre-assembles with U4/U6 snRNPs to form a [U4/U6:U5] tri-snRNP complex required for pre-mRNA splicing. Dim1 interacts with multiple splicing-associated proteins, suggesting that it functions at multiple control points in the splicing of pre-mRNA as part of a large spliceosomal complex involving many protein-protein interactions. U5 snRNP contains seven core proteins (common to all snRNPs) and nine U5-specific proteins, one of which is Dim1. Dim1 adopts a thioredoxin fold but does not contain the redox active CXXC motif. It is essential for G2/M phase transition, as a consequence to its role in pre-mRNA splicing.

 12-88 5.25e-06

TRX family; composed of two groups: Group I, which includes proteins that exclusively encode a TRX domain; and Group II, which are composed of fusion proteins of TRX and additional domains. Group I TRX is a small ancient protein that alter the redox state of target proteins via the reversible oxidation of an active site dithiol, present in a CXXC motif, partially exposed at the protein's surface. TRX reduces protein disulfide bonds, resulting in a disulfide bond at its active site. Oxidized TRX is converted to the active form by TRX reductase, using reducing equivalents derived from either NADPH or ferredoxins. By altering their redox state, TRX regulates the functions of at least 30 target proteins, some of which are enzymes and transcription factors. It also plays an important role in the defense against oxidative stress by directly reducing hydrogen peroxide and certain radicals, and by serving as a reductant for peroxiredoxins. At least two major types of functional TRXs have been reported in most organisms; in eukaryotes, they are located in the cytoplasm and the mitochondria. Higher plants contain more types (at least 20 TRX genes have been detected in the genome of Arabidopsis thaliana), two of which (types f amd m) are located in the same compartment, the chloroplast. Also included in the alignment are TRX-like domains which show sequence homology to TRX but do not contain the redox active CXXC motif. Group II proteins, in addition to either a redox active TRX or a TRX-like domain, also contain additional domains, which may or may not possess homology to known proteins.

 10-88 6.37e-05

TRX domain, PICOT (for PKC-interacting cousin of TRX) subfamily; PICOT is a protein that interacts with protein kinase C (PKC) theta, a calcium independent PKC isoform selectively expressed in skeletal muscle and T lymphocytes. PICOT contains an N-terminal TRX-like domain, which does not contain the catalytic CXXC motif, followed by one to three glutaredoxin domains. The TRX-like domain is required for interaction with PKC theta. PICOT inhibits the activation of c-Jun N-terminal kinase and the transcription factors, AP-1 and NF-kB, induced by PKC theta or T-cell activating stimuli.
