HHATL Proteins

Protein Information

The Protein-cysteine N-palmitoyltransferase HHAT-like protein (HHATL), also known at the mammalian glycerol uptake/transporter 1 (Gup1) is a homolog of the S. cerevisiae Gup1. It is an endoplasmic reticulum (ER) membrane protein that co-localizes with the mammalian hedgehog acyltransferse Skn and interferes with its N-terminal palmitoylation of Sonic hedgehog (SHH), suggesting that HHATL acts as a negative regulator for N-terminal palmitoylation of SHH. HHATL is highly expressed in normal skin, but becomes down-regulated in skin squamous cell carcinoma, suggesting it may play a role in its development.
