In molecular biology, palmitoylation is the covalent attachment of fatty acids, such as palmitic acid, to cysteine (S-palmitoylation) and less frequently to serine and threonine (O-palmitoylation) residues of proteins, which are typically membrane proteins. [2] The precise function of palmitoylation depends on the particular protein being ...
RU-SKI 43 inhibits the activity of SHHat, an enzyme that catalyzes the palmitoylation of Shh. [56] Since palmitoylation is essential for the activity of Shh, [57] inhibition of SHHat by RU-SKI 43 inhibits Shh signaling in cancer cells. [58] [59] 5E1, a monoclonal antibody against Shh, has been shown to inhibit medulloblastoma growth in mouse ...
Palmitoylation S-palmitoylation (i.e. attachment of palmitic acid) is a reversible protein modification in which a palmitic acid is attached to a specific cysteine residue via thioester linkage. [ 2 ] [ 11 ] The term S-acylation can also be used when other medium and long fatty acids chains are also attached to palmitoylated proteins.
In palmitoleoylation, a palmitoleoyl group (derived from palmitoleic acid, pictured above) is added.. Palmitoleoylation is type of protein lipidation where the monounsaturated fatty acid palmitoleic acid is covalently attached to serine or threonine residues of proteins.
GAP43, is a nervous tissue-specific cytoplasmic protein that can be attached to the membrane via a dual palmitoylation sequence on cysteines 3 and 4. This sequence targets GAP43 to lipid rafts. It is a major protein kinase C substrate and is considered to play a key role in neurite formation, regeneration, and plasticity.
In molecular biology the DHHC domain is a protein domain that acts as an enzyme, which adds a palmitoyl chemical group to proteins in order to anchor them to cell membranes. The DHHC domain was discovered in 1999 and named after a conserved sequence motif found in its protein sequence . [ 1 ]
The Rho family of GTPases is a family of small (~21 kDa) signaling G proteins, and is a subfamily of the Ras superfamily.The members of the Rho GTPase family have been shown to regulate many aspects of intracellular actin dynamics, and are found in all eukaryotic kingdoms, including yeasts and some plants.
