Proteomics of Naja naja venom from the Western Ghats of India


ABSTRACT: This project mainly aims to characterize the complex toxic components present in the venom of Indian cobra (Naja naja) from the Western Ghats of India. Naja naja (NN) is native to the Indian subcontinent and is also found in Pakistan, Sri Lanka, Bangladesh and Southern Nepal. It is a highly venomous snake species of genus Naja of the Elapidae family. They are seen in wide habitats like plains, dense or open forests, rocky terrains, wetlands, agricultural lands, and outskirts of villages and even in highly populated urban areas. This species has been included in the ‘Big 4’ category of venomous snake species that accounts for majority of morbidity and mortality cases in India. Therefore, exploring the venom proteome of Naja naja is decisive to develop and design new antivenom and therapeutics against its envenomation. The venom proteome of Naja naja was characterized through various orthogonal separation strategies and identification strategies. In order to achieve this the crude venom components were resolved on a 12% SDS page. Also, the venom was decomplexed through reversed-phase HPLC followed by SDS analysis. Further each of the bands were subjected to in-gel digestion using trypsin, chymotrypsin and V8 proteases. All the digested peptides were then subjected to Q-TOF LC-MS/MS analysis.
