TIMMDC1 is a protein that in humans is encoded by the TIMMDC1 gene .[1] [2] chaperone protein involved in constructing the membrane arm of mitochondrial Complex I .[3] 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 .[4] 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.[5]
Structure 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.[2] amino acids .[6] [7] 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.[8]
Function 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.[3]
Clinical Significance 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 .[4] 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 COL3A1 [5]
Interactions 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.[9] [3] ECSIT -TMEM126B -ACAD9 -NDUFAF1 assembly factor complex (MCIA complex).[8]
