Retinal rod rhodopsin-sensitive cGMP 3',5'-cyclic phosphodiesterase subunit delta - Q9XT54 (PDE6D_CANLF)


Protein Feature View of PDB entries mapped to a UniProtKB sequence  

Promotes the release of prenylated target proteins from cellular membranes (By similarity). Modulates the activity of prenylated or palmitoylated Ras family members by regulating their subcellular location (By similarity). Required for normal ciliary targeting of farnesylated target proteins, such as INPP5E (By similarity). Modulates the subcellular location of target proteins by acting as a GTP specific dissociation inhibitor (GDI) (By similarity). Increases the affinity of ARL3 for GTP by several orders of magnitude. Stabilizes ARL3-GTP by decreasing the nucleotide dissociation rate (By similarity). UniProt

Subunit Structure
Interacts with the prenylated catalytic subunits of PDE6, an oligomer composed of two catalytic chains (PDE6A and PDE6B) and two inhibitory chains (gamma); has no effect on enzyme activity but promotes the release of the prenylated enzyme from cell membrane (By similarity). Interacts with prenylated GRK1 and GRK7 (By similarity). Interacts with prenylated INPP5E (By similarity). Interacts with prenylated Ras family members, including HRAS, KRAS, NRAS, RAP2A, RAP2C and RHEB (By similarity). Interacts with RAB13 (prenylated form); dissociates RAB13 from membranes (By similarity). Interacts with RPGR (By similarity). Interacts with ARL2 (By similarity). Interacts with ARL3; the interaction occurs specifically with the GTP-bound form of ARL3 (By similarity). Interaction with ARL2 and ARL3 promotes release of farnesylated cargo proteins (By similarity). 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 Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  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.
