چکیده
|
Gene targeting of mouse sushi-ichi-related retrotransposon homologue 11/zinc finger cchc domain-containing 16 (sirh11/zcchc16) causes abnormal behaviors related to cognition,including attention,impulsivity and working memory. sirh11/zcchc16 encodes a cchc type of zinc-finger protein that exhibits high homology to an ltr retrotransposon gag protein. upon microdialysis analysis of the prefrontal cortex region,the recovery rate of noradrenaline (na) was reduced compared with dopamine (da) after perfusion of high potassium-containing artificial cerebrospinal fluid in knockout (ko) mice. these data indicate that sirh11/zcchc16 is involved in cognitive function in the brain,possibly via the noradrenergic system,in the contemporary mouse developmental systems. interestingly,it is highly conserved in three out of the four major groups of the eutherians,euarchontoglires,laurasiatheria and afrotheria,but is heavily mutated in xenarthran species such as the sloth and armadillo,suggesting that it has contributed to brain evolution in the three major eutherian lineages,including humans and mice. sirh11/zcchc16 is the first sirh gene to be involved in brain function,instead of just the placenta,as seen in the case of peg10,peg11/rtl1 and sirh7/ldoc1. © 2015 irie et al.
