Fig. 4From: The homozygous pathogenic variant of the POMGNT1 gene identified using whole-exome sequencing in Iranian family with congenital hydrocephalusThe POMGNT1 protein’s 3D structure and a schematic depiction of its subunits. The canonical isoform of the POMGNT1 protein (Q8WZA1-1) comprises the cytoplasmic tail, transmembrane domain (Signal-anchor for type II membrane protein), catalytic and carbohydrate-binding stem domains. Tryptophan is topologically positioned at p.25 of the POMGNT1 protein and is part of the cytoplasmic tail (Met1 to Arg37)Back to article page
