The transgenic construct contains an untagged human profilin 1 (PFN1) cDNA sequence (420 bp) under the direction of mouse prion protein promoter. Expression is detected in brain, spinal cord, and to a lesser extent in skeletal muscle. The transgene is not expressed in the liver. Founder line 850 was identified with total PFN1 protein levels in spinal cord at ~4-fold greater levels compared to endogenous mouse PFN1 protein levels in non-transgenic mice. (J:241428)
