The mouse promoter drives brain-specific expression of an HA-tagged 2.3 kb fragment of the mouse cDNA. Lines 1 (2.5- to 5.1-fold increased expression) and 10 (1.5- to 2.5-fold increased expression) were generated. Line 10 contains 14 copies of the transgene inserted into a long intron. Transcript expression of splice variant B is decreased in the testis. (J:162852, J:203814)
