Transient receptor potential protein - P19334 (TRP_DROME)

 

Protein Feature View of PDB entries mapped to a UniProtKB sequence  

  • Number of PDB entries for P19334: 1
 
Function
A light-sensitive calcium channel that is required for inositide-mediated Ca(2+) entry in the retina during phospholipase C (PLC)-mediated phototransduction. Ca(2+) influx may then feed back and inhibit PLC, thereby facilitating phosphatidylinositol 4,5 bisphosphate (PIP2) recycling. Trp and trpl act together in the light response, though it is unclear whether as heteromultimers or as distinct units, and are activated by fatty acids and metabolic stress. Also required for olfactory adaptation and may be involved in olfactory system development. UniProt

Subunit Structure
The C-terminus interacts with a PDZ domain of inaD to form the core of the inaD signaling complex. Other members of the complex include norpA (PLC), inaC (PKC), and possibly trpl, ninaC, FKBP59, calmodulin and rhodopsin. Forms homomultimers and heteromultimers with trpl. Interaction with trpl is mediated in part by the N-terminal region and the transmembrane domains. Also interacts, though to a lower extent, with Trpgamma. 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
