The GFP-CETN2 transgene was designed with a chicken beta-actin promoter (with cytomegalovirus immediate early enhancer and beta-actin intron) upstream of an EGFP-centrin 2 fusion protein (containing the full length human centrin 2 cDNA cloned in-frame into the C-terminal of enhanced green fluorescent protein), and followed by a beta-globin polyA sequence. Two lines were maintained (18-1 and 3-4) and line 3-4 was donated to The Jackson Laboratory. These lines show consistent, robust expression of GFP in centrosomes (particularly in cerebellar granule cells).
