    basic FUNCTION
  • mitochondrial multifunctional enzyme, which catalyzes the oxidation of steroid modulators of GABA type A (GABAA) receptors, steroid hormones, and xenobiotics (Yang 2009)
  • acting on a number of substrates including steroid, cholic acids, fatty acids preferentially short chain methyl-branched acyl-CoAs
  • may be contributing to the neuronal dysfunction associated with Alzheimer disease
  • involved in cognitive functions, through metabolism of isoleucine and neuroactive steroid
  • mitochondrial enzyme important in isoleucine and branched-chain fatty-acid degradation
  • is an essential component of mitochondrial Ribonuclease P (RNase P), an enzyme required for mitochondrial tRNA processing, but little is known about the role of HSD10 in RNase P function
  • homotetrameric mitochondrial multifunctional enzyme catalyzes the oxidation of neuroactive steroids and the degradation of isoleucine
  • play a protective role in cells undergoing stress
  • TRMT10C along with HSD17B10 and KIAA0391, form the mitochondrial ribonuclease P (mt-RNase P) complex that cleaves the 5prime ends of mt-tRNAs from polycistronic precursor transcripts
  • subunits TRMT10C and HSD17B10 form a subcomplex that binds conserved mitochondrial tRNA elements, including the anticodon loop, and positions the tRNA for methylation
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism lipid/lipoprotein
    signaling
    a component
  • RNase P consists of three different proteins TRMT10C, MRPP2 (HSD17B10) and MRPP3 (KIAA0391), each of which is essential for RNase P function
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • is important for the maintenance of normal TRMT10C protein levels
  • TRMT10C and HSD17B10 both deliver the pre-tRNA substrate and activate KIAA0391 through an induced-fit process
  • presence of PRORP can enhance the methylation activity of TRMT10C/HSD17B10
