TTC19 encodes a protein with a tetratricopeptide repeat (TPR) domain containing several TPRs of about 34 aa each. Additionally we are shipping TTC19 Antibodies (15) and many more products for this protein.

UQCRFS1 produces N-terminal polypeptides, which remain bound to holocomplex III. We show that, in normal (show UQCRFS1 Proteins)conditions, these UQCRFS1 fragments are rapidly removed, but when TTC19 is absent (show UQCRFS1 Proteins) they accumulate within complex III, causing its structural and functional impairment.
TTC19 preserves the structural and functional integrity of mitochondrial respiratory complex III. UQCRFS1 (show UQCRFS1 Proteins) produces N-terminal polypeptides, which remain bound to holocomplex III. UQCRFS1 (show UQCRFS1 Proteins) fragments are rapidly removed, but when TTC19 is absent they accumulate within complex III, causing its structural and functional impairment.
TTC19-deficient mitochondrial complex III deficiency displays substantial phenotypic variation. (Review)
This study showed that TTC19 deficient patients do show characteristic clinical and neuroimaging features, which may facilitate diagnosis of this yet rare disorder; normal MRC complex III activity does not exclude the diagnosis.
A TTC19 mutation in spinocerebellar ataxia is identified in an Asian population.
The mutation resulted in almost complete absence of TTC19 protein, defective assembly of CIII in muscle, and enhanced production of reactive oxygen species in cultured skin fibroblasts.
TTC19 is a putative cIII assembly factor whose disruption is associated with severe neurological abnormalities in humans and flies.
This gene encodes a protein with a tetratricopeptide repeat (TPR) domain containing several TPRs of about 34 aa each. These repeats are found in a variety of organisms including bacteria, fungi and plants, and are involved in a variety of functions including protein-protein interactions. This protein is embedded in the inner mitochondrial membrane and is involved in the formation of the mitochondrial respiratory chain III. It has also been suggested that this protein plays a role in cytokinesis. Mutations in this gene cause mitochondrial complex III deficiency. Alternatively spliced transcript variants have been found for this gene.
