ZDHHC5 (zinc finger, DHHC-type containing 5) is a member of the family of integral membrane proteins called DHHC (Asp-His-His-Cys). This family has its palmitoyl acyltransferases (PAT) activity conserved through Saccharomyces cerevisiae to mammals. This family has 23 identified members in humans, out of which 17 exhibit PAT activity. ZDHHC5 protein and the mRNA are highly expressed in neurons. It is found in dendrites, in dendritic shafts, and rarely in dendritic spine. ZDHHC5 gene is localized to human chromosome 11. It has the characteristic DHHC domain, and has a highly elongated C-terminal. This C-terminal contains PDZ-binding domain, which is specific for type II PDZ-ligand

Application: Anti-ZDHHC5 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: ZDHHC5 (zinc finger, DHHC-type containing 5) is a palmitoyl acyltransferase (PAT), which has its three cysteine residues S-acylated, within the CCX7-13C(S/T) motif. It is responsible for the palmitoylation of somatostatin receptor subtype 5 (SSTR5), which is a GPCR (G-protein coupled receptor). It might also be involved in the palmitoylation of other GPCRs, especially in the brain. This might explain its role in learning, memory and synaptic function. Also this protein is highly expressed in neurons, and might have an essential regulatory role in the neurons. Suppression of ZDHHC5 in mice, shows reduced learning capabilities, and this protein is also linked with neuropsychiatric disorders. This gene locus is also associated with bipolar disorder. It also palmitoylates GRIP1 (Glutamate receptor-interacting protein 1)b protein, and targets it to the endosomes of dendritic cells. This way it controls the trafficking of AMPA-R (a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor).
