NADH dehydrogenase [ubiquinone] iron-sulfur protein 7, mitochondrial; Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone (213 aa)

Solute carrier family 13 member 2; Cotransport of sodium ions and dicarboxylates such as succinate and citrate; Solute carriers (641 aa)

Matrilin-3; Major component of the extracellular matrix of cartilage and may play a role in the formation of extracellular filamentous networks; Matrilins (486 aa)

Thyroid receptor-interacting protein 11; Binds the ligand binding domain of the thyroid receptor (THRB) in the presence of triiodothyronine and enhances THRB- modulated transcription. Golgi auto-antigen; probably involved in maintaining cis-Golgi structure (1979 aa)

Bifunctional 3’-phosphoadenosine 5’-phosphosulfate synthase 1; Bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5’-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3’-phosphoadenylylsulfate (PAPS- activated sulfate donor used by sulfotransferase). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate- activation pathway. Required [...] (624 aa)

Collagen alpha-2(IX) chain; Structural component of hyaline cartilage and vitreous of the eye; Collagen proteoglycans (689 aa)

Solute carrier family 13 member 3; High-affinity sodium-dicarboxylate cotransporter that accepts a range of substrates with 4-5 carbon atoms. The stoichiometry is probably 3 Na(+) for 1 divalent succinate; Belongs to the SLC13A/DASS transporter (TC 2.A.47) family. NADC subfamily (602 aa)
