Palmitoyltransferase that catalyzes the addition of palmitate onto various protein substrates and is involved in a variety of cellular processes. Has no stringent fatty acid selectivity and in addition to palmitate can also transfer onto target proteins myristate from tetradecanoyl-CoA and stearate from octadecanoyl-CoA (By similarity). Plays a role in axonogenesis (PubMed:26232532). hexadecanoyl-CoA + L-cysteinyl-[protein] = CoA + S-hexadecanoyl-L-cysteinyl-[protein] L-cysteinyl-[protein] + tetradecanoyl-CoA = CoA + S-tetradecanoyl-L-cysteinyl-[protein] L-cysteinyl-[protein] + octadecanoyl-CoA = CoA + S-octadecanoyl-L-cysteinyl-[protein] Probably maternally supplied, the zygotic expression becomes significative at 2.75 hpf and then decreases after 18 hpf but is still detected at 24 hpf (PubMed:26056731, PubMed:27235108). Highly expressed in the developing central nervous system from the presumptive telencephalon to the caudal tip of the spinal cord (PubMed:26232532). The DHHC domain is required for palmitoyltransferase activity. Autopalmitoylated. Morpholino knockdown of the protein does not apparently affect embryo development (PubMed:26232532). However, the motility of morphants is markedly reduced from 3 days post-fertilization onwards (PubMed:26232532). This is associated with a significant defect in the axonal outgrowth of spinal motor neurons without affecting neuron generation (PubMed:26232532). Belongs to the DHHC palmitoyltransferase family. AKR/ZDHHC17 subfamily.
