Aim:
To clone and analyse the coding cDNA sequence of alpha1, beta2 and gamma2 subunit of GABAA receptor in American king Pigeon.
Methods:
Withdrew total RNA from the American king pigeon brain, reverse transcribing general primers to acquire a gene set cDNA. Designing specific primers of three subunit mRNA of the GABAA receptor, by RT-PCR respectively expanded the conservative gene of al subunit, beta2 subunit and gamma2 subunit of GABAA receptor, and carried on clone, plastid identification and the sequence measurese of three genes.
Results:
The experiment on sequence measures has succeeded that sequence analysis indicated that lengths of the conservative gene of alpha1 subunit, beta2 subunit and gamma2 subunit of GABAA receptor was respectively 899 bp, 597 bp and 563 bp, homology on reference sequence was respectively 94.99%, 94.64% and 96.28%.
Conclusion:
Homology is high on the conservative gene of alpha1 subunit, beta2 subunit and gamma2 subunit of GABAA receptor of brain tissue of pigeon and chicken but there is a discriminating characteristic in different kinds of animals.
