54S ribosomal protein L36, mitochondrial - P36531 (RM36_YEAST)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Component of the mitochondrial ribosome (mitoribosome), a dedicated translation machinery responsible for the synthesis of mitochondrial genome-encoded proteins, including at least some of the essential transmembrane subunits of the mitochondrial respiratory chain. The mitoribosomes are attached to the mitochondrial inner membrane and translation products are cotranslationally integrated into the membrane (PubMed:25609543, PubMed:24675956). Overexpression of bL31m suppresses mutations in the COX2 leader peptide-encoding and initiation codon regions (PubMed:11259585, PubMed:15166137). UniProt

Subunit Structure
Component of the mitochondrial large ribosomal subunit (mt-LSU). Mature yeast 74S mitochondrial ribosomes consist of a small (37S) and a large (54S) subunit. The 37S small subunit contains a 15S ribosomal RNA (15S mt-rRNA) and 34 different proteins. The 54S large subunit contains a 21S rRNA (21S mt-rRNA) and 46 different proteins. UniProt
Contains two functional domains. The central domain is sufficient for general mitochondrial translation but not suppression of COX2 mutants. The C-terminus sequence is sufficient for dosage suppression of COX2 mutants. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB
  • Secstruc: Secondary structure projected from representative PDB entries onto the UniProt sequence.
Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
