Protein Domain : CRAL-TRIO lipid binding domain IPR001251

Type  Domain
Description  The CRAL-TRIO domain is a protein structural domain that binds small lipophilic molecules [ ]. The domain is named after cellular retinaldehyde-binding protein (CRALBP) and TRIO guanine exchange factor.The CRAL-TRIO domain is found in GTPase-activating proteins (GAPs), guanine nucleotide exchange factors (GEFs) and a family of hydrophobic ligand binding proteins, including the yeast SEC14 protein and mammalian retinaldehyde- and alpha-tocopherol-binding proteins. The domain may either constitute all of the protein or only part of it [ , , , ].The structure of the domain in SEC14 proteins has been determined [ ]. The structure contains several alpha helices as well as a beta sheet composed of 6 strands. Strands 2,3,4 and 5 form a parallel beta sheet with strands 1 and 6 being anti-parallel. The structure also identified a hydrophobic binding pocket for lipid binding.
