PHYHIPL (Phytanoyl-CoA 2-Hydroxylase Interacting Protein-Like): PHYHIPL is a protein associated with the peroxisomal degradation pathway, particularly involved in the metabolism of branched-chain fatty acids and bile acid intermediates. It contributes to lipid metabolism and the maintenance of cellular lipid homeostasis. Although its exact functions are still being defined, PHYHIPL may play a role in metabolic disorders linked to defective lipid processing.
