Atp2b4tm1Ges/Atp2b4tm1Ges sperm tails exhibit an increase in the number of condensed mitochondria

reproductive system
asthenozoospermia ( J:91844 )
• hyperactivated sperm motility is severely impaired with most mutant sperm non-motile after 90 min in conditions that should result in hyperactivation
• in hyperactivating conditions mutant sperm have significantly more condensed mitochondria compared to wild-type sperm
• mutant sperm have normal motility in the epididymis
male infertility ( J:91844 )
• males but not females are infertile

Atp2b4tm1Ges/Atp2b4tm1Ges portal vein smooth muscle shows an increase in apoptosis

behavior/neurological
excessive scratching ( J:91844 )
• excessive scratching is seen around the jaw and is correlated with an enlarged submandibular gland
• this phenotype is not seen on an inbred Black Swiss background

immune system
enlarged submandibular lymph nodes ( J:91844 )
• the submandibular gland is enlarged
• this phenotype is not seen on an inbred Black Swiss background

reproductive system
male infertility ( J:91844 )
• males but not females are infertile

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

cardiovascular system
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
