Diazepam-binding inhibitor (DBI), also known as endozepine (EP) or acyl-CoA-binding protein (ACBP), is a conserved protein involved in various cellular processes.
Understanding the molecular characteristics of DBI/EP/ACBP in different species aids in comparative studies of protein function and evolution.
Purpose of the Study:
To isolate and sequence the full-length cDNA encoding common carp DBI/EP/ACBP.
To analyze the deduced amino acid sequence and compare it with homologous proteins from other species.
Main Methods:
Isolation and sequencing of full-length cDNA from common carp.
Bioinformatic analysis of the deduced amino acid sequence.
Sequence alignment and identity comparison with mammalian, amphibian, avian, and yeast DBI/EP/ACBP.
Main Results:
A full-length cDNA sequence for common carp DBI/EP/ACBP was successfully obtained.
The deduced protein consists of 87 amino acids, lacking a signal peptide.
High sequence identity was observed between common carp and human (77%) and bovine (78%) DBI/EP/ACBP, with lower identity to rat, frog, duck, and yeast orthologs.
Conclusions:
The common carp DBI/EP/ACBP sequence has been characterized.
The findings provide insights into the evolutionary conservation of DBI/EP/ACBP across vertebrates and yeast.
This study contributes to the understanding of DBI/EP/ACBP function in fish models.
