Figure 1. Mouse CASZ1a (mCASZ1a) and CASZ1b (mCASZ1b) co-exist during neurogenesis and exhibit different patterns of expression.

Figure 1

A. CASZ1a and CASZ1b transcript structure (top). Exon 16 is differently spliced to produce these two transcripts; CASZ1a and CASZ1b protein structure (bottom); CASZ1b lacks the C-terminal region of CASZ1a, which includes 6 zinc fingers. B. mCASZ1a and mCASZ1b mRNA level in neuronal tissues were detected by real time PCR using mCASZ1a and mCASZ1b specific primers. The two isoforms are dynamically expressed in the nervous system during development with mCASZ1a having a relatively higher level of expression compared to mCASZ1b. C. The ratio of mCASZ1a and mCASZ1b mRNA varied during development in different regions of the brain: a. Medulla; b. Frontal, Posterior, Enthorithinal cortex and Hippocampus; c. Hypothalamus, Olfactory bulb; d. Midbrain, Spinal cord, Thalamus, Pons and Striatum.
