Protein nanos - P25724 (NANOS_DROME)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

 
Function
Maternal RNA-binding protein that is required for germ cells proliferation and self-renewal. Acts by forming a complex with pum and brat that regulates translation and mRNA stability. The complex binds to the Nanos Response Element (NRE), a 16 bp sequence in the hb mRNA 3'-UTR and prevents its translation. Controls posterior development. Rescuing factor for the abdominal defect of posterior group mutants. The other posterior group genes are not required for nanos function but rather play a role in localization or distribution of nanos protein. UniProt

Subunit Structure
Interacts with pum and brat. Acts via the formation of a quaternary complex composed of pum, nos, brat and the 3'-UTR mRNA of hb. Interacts with cup. Binds RNA with no specificity. UniProt
Domain
The Nanos-type zinc finger is composed of two C2HC motifs, each motif binding one molecule of zinc. The presence of the zinc molecules is essential for the translation repression activity of the protein. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
