Enables palmitoyltransferase activity. Involved in N-terminal peptidyl-L-cysteine N-palmitoylation. Acts upstream of or within protein palmitoylation and smoothened signaling pathway. Predicted to be located in Golgi apparatus. Predicted to be active in endoplasmic reticulum. Is expressed in branchial arch; embryo; embryo ectoderm; and limb. Used to study chondrodysplasia-pseudohermaphroditism syndrome. Human ortholog(s) of this gene implicated in chondrodysplasia-pseudohermaphroditism syndrome. Orthologous to human HHAT (hedgehog acyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
