muscle
decreased vasoconstriction ( J:91844 )
• portal vein contractility is reduced and increased apoptosis is seen smooth muscle cells surrounding the portal vein after 4 hours in culture compared to wild-type mice
• Background Sensitivity: this phenotype is not as severe as for Atp2b4tm1Ges homozygotes on a mixed 129/SvJ and Black Swiss background
