Figure 4From: Knobbed acrosome defect is associated with a region containing the genes STK17b and HECW2 on porcine chromosome 15Alignment of HECW2 protein sequences at the detected polymorphism positions in various species. The only difference between control (Yorkshire) and KA-affected (Akr) animals was a change from isoleucine to threonine (SNP). However, this change was also present in the human protein sequence. Furthermore, a three aa deletion was identified when compared with the pig reference sequence.Back to article page
