PDE6D
Description
The PDE6D (phosphodiesterase 6D) is a protein-coding gene located on chromosome 2.
Retinal rod rhodopsin-sensitive cGMP 3',5'-cyclic phosphodiesterase subunit delta is an enzyme that in humans is encoded by the PDE6D gene. PDE6D was originally identified as a fourth subunit of rod cell-specific cGMP phosphodiesterase (PDE) (EC 3.1.4.35). The precise function of PDE delta subunit in the rod specific GMP-PDE complex is unclear. In addition, PDE delta subunit is not confined to photoreceptor cells but is widely distributed in different tissues. PDE delta subunit is thought to be a specific soluble transport factor for certain prenylated proteins and Arl2-GTP a regulator of PDE-mediated transport.
Promotes the release of prenylated target proteins from cellular membranes (PubMed:9712853). Modulates the activity of prenylated or palmitoylated Ras family members by regulating their subcellular location (PubMed:22002721, PubMed:23698361). Required for normal ciliary targeting of farnesylated target proteins, such as INPP5E (PubMed:24166846). 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). {ECO:0000250|UniProtKB:O55057, ECO:0000269|PubMed:10518933, ECO:0000269|PubMed:22002721, ECO:0000269|PubMed:23559067, ECO:0000269|PubMed:23698361, ECO:0000269|PubMed:24166846, ECO:0000269|PubMed:9712853}
PDE6D is also known as JBTS22, PDED.
