Cox17 is essential for the assembly of functional cytochrome c oxidase (CCO) and for delivery of copper ions to the mitochondrion for insertion into the enzyme in yeast. The structure of Cox17 shows the protein to have an unstructured N-terminal region followed by two helices and several unstructured C-terminal residues. The Cu(I) binding site has been modelled as two-coordinate with ligation by conserved residues Cys23 and Cys26. Length = 48

Alignment of this protein with related members showed the presence of three subgroups of proteins, which are called the S (Small), N (N-terminal extended) and C (C-terminal extended) subgroups. All three sub-groups of proteins have in common that they contain a predicted conserved [coiled coil 1]-[helix 1]-[coiled coil 2]-[helix 2] domain (CHCH domain). Within each helix of the CHCH domain, there are two cysteines present in a C-X9-C motif. The N-group contains an additional double helix domain, and each helix contains the C-X9-C motif. This family contains a number of characterised proteins: Cox19 protein - a nuclear gene of Saccharomyces cerevisiae, codes for an 11 kDa protein (Cox19p) required for expression of cytochrome oxidase. Because cox19 mutants are able to synthesise the mitochondrial and nuclear gene products of cytochrome oxidase, Cox19p probably functions post-translationally during assembly of the enzyme. Cox19p is present in the cytoplasm and mitochondria, where it exists as a soluble intermembrane protein. This dual location is similar to what was previously reported for Cox17p, a low molecular weight copper protein thought to be required for maturation of the CuA centre of subunit 2 of cytochrome oxidase. Cox19p have four conserved potential metal ligands, these are three cysteines and one histidine. Mrp10 - belongs to the class of yeast mitochondrial ribosomal proteins that are essential for translation []. Eukaryotic NADH-ubiquinone oxidoreductase 19 kDa (NDUFA8) subunit []. The CHCH domain was previously called DUF657 []. ; PDB: 2ZXT_A 3A3C_A 2L0Y_A 2K3J_A.

MTCP1 is alternatively spliced to produce two completely distinct proteins: the small mitochondrial protein, p8MTCP1, and the protein p13MTCP1, which shows strong homology to another oncogene product, p14TCL1. While p13MTCP1 expression appears to be restricted to mature T-cell proliferation with t(X,14) translocations, the mitochondrial p8MTCP1 is expressed at low levels in most human tissues, and is over-expressed in the proliferating T-cells. The biological function of p8MTCP1 is still unknown, but it appears to play a role in oncogenesis. The structure of p8MTCP1 reveals a disulphide-rich, irregular array of three helices [].; PDB: 2HP8_A 1EI0_A 1HP8_A.

In Saccharomyces cerevisiae (Baker's yeast) the gene YKL053C-A (MDM35) O60200 from SWISSPROT is one of the genes essential for maintenance of normal mitochondrial distribution and morphology (MDM) []; wherease in Homo sapiens (Human), p53CSV, O43715 from SWISSPROT is a direct transcriptional target for p53 and appears to be a cell-survival mediator in response to genotoxic stress including low-levels of DNA damage. It is suggested that p53CSV modulates the apoptotic pathway through interaction with HSP70 and Apaf-1 thereby inhibiting activation of procaspase-3 and procaspase-9 [].

Alignment of this protein with related members showed the presence of three subgroups of proteins, which are called the S (Small), N (N-terminal extended) and C (C-terminal extended) subgroups. All three sub-groups of proteins have in common that they contain a predicted conserved [coiled coil 1]-[helix 1]-[coiled coil 2]-[helix 2] domain (CHCH domain). Within each helix of the CHCH domain, there are two cysteines present in a C-X9-C motif. The N-group contains an additional double helix domain, and each helix contains the C-X9-C motif. This family contains a number of characterised proteins: Cox19 protein - a nuclear gene of Saccharomyces cerevisiae, codes for an 11 kDa protein (Cox19p) required for expression of cytochrome oxidase. Because cox19 mutants are able to synthesise the mitochondrial and nuclear gene products of cytochrome oxidase, Cox19p probably functions post-translationally during assembly of the enzyme. Cox19p is present in the cytoplasm and mitochondria, where it exists as a soluble intermembrane protein. This dual location is similar to what was previously reported for Cox17p, a low molecular weight copper protein thought to be required for maturation of the CuA centre of subunit 2 of cytochrome oxidase. Cox19p have four conserved potential metal ligands, these are three cysteines and one histidine. Mrp10 - belongs to the class of yeast mitochondrial ribosomal proteins that are essential for translation []. Eukaryotic NADH-ubiquinone oxidoreductase 19 kDa (NDUFA8) subunit []. The CHCH domain was previously called DUF657 []. ; PDB: 2ZXT_A 3A3C_A 2L0Y_A 2K3J_A.
