Detecting splicing variants of FOXP2 and its protein expression in chicken brain

The whole cDNA sequence of chicken FOXP2 gene was obtained by 3' and 5' RACE and the length was 3839 bp, getting four splicing variants for protein isoforms (707 AA, 706AA, 687AA, 684AA). The four splicing variants were common to Zang chicken, White Plymouth Rock, Beijing fat chicken, White leghorns and Rhode Island Red by the detection of a combination of PCR and sequencing and according to two main splicing variants, two antibodies were produced to be used to detect equivalent expression in chicken brain such as cortex, striatum, mesencephalon, thalamus and hypothalamus, in White leghorns, (male and female) by immunohistochemistry. The results showed that different FOXP2 mRNA and protein expression had no spatial difference.
