Integration of transcriptomic and proteomic approaches for snake venom profiling.

Area of Science:

• Zoology
• Biochemistry
• Genomics

Background:

• Snake venoms exhibit significant protein and peptide sequence variation, even within a single species.
• Traditional venom characterization methods can be limited by reliance on databases from model organisms.

Purpose of the Study:

• To demonstrate the utility of a combined venom gland transcriptome and proteome methodology for comprehensive venom characterization.
• To provide recommendations for utilizing these integrated approaches.

Main Methods:

• Utilizing a combined venom gland transcriptome and proteome methodology.
• Analyzing data from both published and unpublished studies, including understudied rear-fanged snake species.

Main Results:

• The integrated approach allows for comprehensive characterization of venom components.
• Species-specific venom gland transcriptomes correct for missing unique peptide sequences in general databases.
• Integration of transcriptomics and proteomics enhances the accuracy of venom profiling compared to individual methods.

Conclusions:

• A combined venom gland transcriptome and proteome methodology is crucial for accurate and comprehensive venom profiling.
• This approach is particularly valuable for documenting protein diversity in understudied snake species.
• Recommendations are provided for the effective application of these integrated techniques.
