  ID: LETM1_HUMAN
DESCRIPTION: RecName: Full=LETM1 and EF-hand domain-containing protein 1, mitochondrial; AltName: Full=Leucine zipper-EF-hand-containing transmembrane protein 1; Flags: Precursor;
FUNCTION: Crucial for the maintenance of mitochondrial tubular networks and for the assembly of the supercomplexes of the respiratory chain. Required for the maintenance of the tubular shape and cristae organization.
SUBUNIT: Can form 2 complexes: a major (300kDa) and a minor complex (500-600 kDa). Interacts with BCS1L.
SUBCELLULAR LOCATION: Mitochondrion inner membrane; Single-pass membrane protein.
SIMILARITY: Contains 1 EF-hand domain.
SIMILARITY: Contains 1 LETM1 domain.
SEQUENCE CAUTION: Sequence=CAB63769.2; Type=Erroneous translation; Note=Incomplete prediction of CDS at the C-terminus;

-  Primer design for this transcript
 

Primer3Plus can design qPCR Primers that straddle exon-exon-junctions, which amplify only cDNA, not genomic DNA.
Click here to load the transcript sequence and exon structure into Primer3Plus

Exonprimer can design one pair of Sanger sequencing primers around every exon, located in non-genic sequence.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
