TIMMDC1 is a protein that in humans is encoded by the TIMMDC1 gene. [5] [6] It is a chaperone protein involved in constructing the membrane arm of mitochondrial Complex I. [7] A frameshift mutation in an intron of this gene has been shown to cause failure to thrive, retardation of psychomotor development, infantile-onset hypotonia, and severe neurologic dysfunction. [8] High expression of this gene has been associated with migration of lung cancer cells while depletion of the protein has been shown to affect regulation of apoptosis, the cell cycle, and cell migration. [9]
The TIMMDC1 gene is located on the q arm of chromosome 3 in position 13.33 and spans 25,760 base pairs, with 7 exons. [6] The gene produces a 32.2 kDa protein composed of 285 amino acids. [10] [11] The TIMMDC1 protein has 4 transmembrane domains, with the N-terminal and C-terminal extensions localized in the mitochondrial matrix. TIMMDC1 is a multipass mitochondrial inner membrane protein, predicted to be a member of the 4-pass transmembrane protein family of TIM17-TIM22-TIM23. Its topology is predicted to be analogous to TIMM23. [12]
TIMMDC1 is a chaperone protein involved in the assembly of the mitochondrial Complex I (NADH-ubiquinone oxidoreductase), participating in the construction of the membrane arm of complex I. [7]
A frameshift mutation in intron 5 of the TIMMDC1 gene has been shown to cause severe neurologic dysfunction, infantile-onset hypotonia, retardation of psychomotor development, and failure to thrive. [8] Additionally, high expression of TIMMDC1 has been associated with metastasis of lung carcinoma cells, with depletion of the protein inhibiting growth and migration of 95D lung carcinoma cells. Depletion of TIMMDC1 has also been shown to alter expression of genes involved in the regulation of apoptosis, cell-cycle arrest, and cell migration, including CCNG2 , PTEN , TIMP3 , and COL3A1 . [9]
The TIMMDC1 protein interacts with the intermediate 315 kDa subcomplex of incompletely assembled complex I and has interactions with FATE1, in addition to about 60 other proteins. [13] [7] TIMMDC1 associates reciprocally with multiple components of the ECSIT-TMEM126B-ACAD9-NDUFAF1 assembly factor complex (MCIA complex). [12]
The ATP5MC1 gene is one of three human paralogs that encode membrane subunit c of the mitochondrial ATP synthase.
HIG1 domain family member 1A (HIGD1A), also known as hypoglycemia/hypoxia inducible mitochondrial protein1-a (HIMP1-a) and hypoxia induced gene 1 (HIG1), is a protein that in humans is encoded by the HIGD1A gene on chromosome 3. This protein promotes mitochondrial homeostasis and survival of cells under stress and is involved in inflammatory and hypoxia-related diseases, including atherosclerosis, ischemic heart disease, and Alzheimer’s disease, as well as cancer.
BTB/POZ domain-containing protein 1 is a protein that in humans is encoded by the BTBD1 gene.
Myotubularin-related protein 6 is a protein that in humans is encoded by the MTMR6 gene.
CCR4-NOT transcription complex subunit 8 is a protein that in humans is encoded by the CNOT8 gene. It is a subunit of the CCR4-Not deadenylase complex.
Growth hormone-inducible transmembrane protein (GHITM), also known as transmembrane BAX inhibitor motif containing protein 5 (TMBIM5), is a protein that in humans is encoded by the GHITM gene on chromosome 10. It is a member of the BAX inhibitor motif containing (TMBIM) family and localizes to the inner mitochondrial membrane (IMM), as well as the endoplasmic reticulum (ER), where it plays a role in apoptosis through mediating mitochondrial morphology and cytochrome c release. Through its apoptotic function, GHITM may be involved in tumor metastasis and innate antiviral responses.
Zinc finger protein 43 is a protein that in humans is encoded by the ZNF43 gene.
Ergosterol biosynthetic protein 28 is a protein that in humans is encoded by the ERG28 gene.
Beta-taxilin is a protein that in humans is encoded by the TXLNB gene.
LisH domain-containing protein ARMC9 is a protein that in humans is encoded by the ARMC9 gene.
Transmembrane protein 47 is a protein that in humans is encoded by the TMEM47 gene.
Activating signal cointegrator 1 complex subunit 3 is a protein that in humans is encoded by the ASCC3 gene.
Uncharacterized protein C6orf89 is a protein that in humans is encoded by the C6orf89 gene.
AP-1 complex-associated regulatory protein is a protein that in humans is encoded by the AP1AR gene.
Synaptotagmin-13 is a protein that in humans is encoded by the SYT13 gene.
Spartan (SPRTN) is a protein that in humans is encoded by the SPRTN gene. It is involved in DNA repair. Ruijs-Aalfs syndrome is an autosomal recessive genetic disorder. Characteristics of this disorder are features of premature aging, chromosome instability and development of hepatocellular carcinoma. Ruijs-Aalfs syndrome arises as a result of mutations in the SPRTN gene that encodes a metalloproteinase employed in the repair of protein-linked DNA breaks.
RNA-binding protein MEX3B is a protein that in humans is encoded by the MEX3B gene.
Mitochondrial pyruvate carrier 2 (MPC2) also known as brain protein 44 (BRP44) is a protein that in humans is encoded by the MPC2 gene. It is part of the Mitochondrial Pyruvate Carrier (MPC) protein family. This protein is involved in transport of pyruvate across the inner membrane of mitochondria in preparation for the pyruvate dehydrogenase reaction.
Zinc finger protein 34 is a protein that in humans is encoded by the ZNF34 gene.
Ankyrin repeat domain-containing protein 13C is a protein that in humans is encoded by the ANKRD13C gene.
