Studies on the protein expression of thermosensitive/Neural development-related gene in tilapia, Oreochromis mossambicus.

Expressed sequence tags (ESTs) are derived from the developing
tilapia brain was established in our lab. There are 9 transcripts were
identified as thermosensitive/Neural development-related gene. The
effects of different temperatures on the ontogenetic expression of
these thermosensitive/Neural development-related gene during the
critical period of brain sexual differentiation were investigated in the
present study. The ontogenetic expression of inhibitor of DNA
binding/differentiation protein 2 (Id2), thermosensitive/Neural
development-related gene, were enhanced by both lower (20¢J) and
higher (32¢J) temperatures before 10 days post-hatching.
In this study, bioinformatics were searched for Id2, which is a
gene with 738 bp of patial cDNA sequence, open reading frame
(ORF) is 411bp, and deduced 137 amino acids of protein sequence.
The protein of Id2 was expressed in a prokaryotic system, BL21
(Escherichia coli) and purified with Ni-NTA affinity chromatography.
Also, the ORF of Id2 was cloned into pEGFP vector, and
plasmid (pEGFP-Id2) was transfected into the eukaryotic system,
mouse neuroblastoma cell (Neuro-2a cell). The distribution of Id2
expressed in the Neuro-2a cell was identified by fluorescence
microscopy.
