What is "hhat"

HHAT (hedgehog acyltransferase) also known as HHAT is a human gene.

The HHAT gene encodes an enzyme that catalyzes N-terminal palmitoylation of sonic hedgehog. Mutations in HHAT produce a phenotype that is similar to loss of hedgehog function. Finally the HHAT protein shares a short but significant sequence similarity to membrane-bound O-acyltransferases.
