+Causes and Effects of Loss of Classical Nonhomologous End Joining Pathway in Parasitic Eukaryotes.

conserved from yeast to mammals) is undetectable ([[Denoeud et al., 2010|biblio/21097902]]).
An alternative or microhomology (MH)-driven end joining pathway is active
and triggers microdeletions at the joining site ([[Deng, Henriet and Chourrout, 2018|biblio/30293719]]).
+ Loss of C-NHEJ is often associated with parasitism, which is not the case in
+ _Oikopleura_ (review in [[Nenarokova and coll., 2019|biblio/31311886]]).
- In line with the above, “There is no H2AX homolog in O. dioica.” (H2AX is
implicated in DNA repair). [[Moosmann and coll., 2011|biblio/21756361]]
- The minor spliceosome could not be found in _Oikopleura_'s genome ([[Marz
