Abstract: Goat is the most preferred domesticated animal in Indian subcontinent. However, the climatic change-induced heat stresscauses a formidable challenge for maintaining optimum productivity. G protein subunit alpha i3 (GNAI3) is one of the genes that may have significant role in heat tolerance mechanism in goats. The caprine GNAI3 gene was searched for homology analysis and its three dimensional protein structure was predicted followed by its validation through in silico approach. Nucleotide sequence-based phylogenetic tree analysis showed that the caprine GNAI3 gene has close evolutionary relationship with that of Ovis aries. Homology modelling of caprine GNAI3 protein was done in MODELLER 9.18 (P1), PHYRE2 (P2), GENO3D (P3) and SWISS MODEL (P4). The modelled structures were further validated after observing the Ramachandran and hydrophobicity plots. In the best of three dimensional protein structure (P4 as produced by SWISS MODEL), 330 (98.8%), three (0.9%) and one (0.3%) amino acid residues were found in favoured region, allowed region and outlier region, respectively. Degree of hydrophobicity of the generated protein structures revealed the presence of alternate hydrophobic and hydrophilic regions. The ligand receptor interaction site of the predicted 3D model was traced out using Discovery Studio 3.5. STRING database revealed protein interactions with Plcb1, Plcb2, Plcb3 and other proteins of G family such as Gnb1, Gnb2, Gnb3,Gnb4, Gng2, Gng4 and Gpsm1. KEGG pathway maps revealed interaction with eNOS, iNOS, VEGF and MAPK, which are reported to be transcribed in response to heat stress. Thus, caprine GNAI3 can be used as a possible biomarker for studying heattolerance mechanism in goats.
