Depositor Comments

Fc-portion contains intronic sequences which improve expression.
See map & sequence file for insert-releasing enzymes (e.g. HindIII / BglII for untagged Nrxn1beta, and HindIII / XhoI for Nrxn1beta-FC-fusion).
The Nrxn 1 beta variant encoded by this plasmid is AS4(-), meaning exon 21 constituting alternatively spliced segment 4 (AS4) (=ENSMUSE00001309616) is absent / skipped.
