Neurotrophic Factor 3 (NTF-3) is a gene that encodes the Neurotrophin 3 (NT-3) protein. The NTF3 gene works as a neurotrophic factor that is responsible for enhancing the development of neuron function. Several disorders in the nervous system have become a discussion topic of health problems, such as a study about NTF-3 in pathophysiology. The aim of this research was to study the phylogenetic and tertiary structure of the protein expressed by the NTF-3 gene in humans. The computation method in this study uses in-silico analysis and data from GenBank with accession code M61180.1, and has a protein product with accession code AAA63231.1. The results of this study show humans are quite closely related to primate species based on phylogenetic bootstrap values. The alignment result of the sequences illustrates a high level of similarities. The NT-3 protein is composed of 257 aa (amino acids) with a weight of 29353.03 Daltons. The number of serine, arginine, and leucine contained in the protein is more than other amino acids, i.e. 24 (9.34%), 22 (8.56), and 22 (8.56%), respectively. The 1-41 and 101-251 amino acid sequences of the protein are the conserved areas of the NT-3 protein. The structure of the protein consists of a beta-sheet and coiled structure without an alpha helix. The polar region of the protein structure consists of several amino acids with polar groups that have hydrophilic properties. The result of the study can be utilized in the further study of genetic information related to the protein expressed by the NTF-3 gene in humans, and its role in pathophysiology.
