Genome annotation: From human genetics to biodiversity genomics

Area of Science:

• Genomics
• Bioinformatics
• Evolutionary Biology

Background:

• Massive sequencing of eukaryotic genomes is imminent, necessitating efficient gene identification.
• Eukaryotic genomes exhibit transcriptional complexity, with protein-coding mRNAs being key to phenotypes.
• Sequence conservation allows for orthology establishment, crucial for cataloging genes.

Purpose of the Study:

• To review protein-coding gene prediction basics.
• To discuss challenges in human genome annotation.
• To propose strategies for eukaryotic genome annotation.

Main Methods:

• Review of gene prediction methodologies.
• Analysis of human genome annotation challenges.
• Development of strategies for cross-eukaryotic annotation.

Main Results:

• A proposed framework for comprehensive eukaryotic gene annotation.
• Identification of key challenges in current genome annotation processes.
• Laying the groundwork for a universal eukaryotic gene catalog.

Conclusions:

• A universal catalog of eukaryotic protein-coding genes is achievable.
• This catalog will illuminate the genomic underpinnings of eukaryotic phenotypes.
• The proposed strategies facilitate a unified approach to genome annotation across the Tree of Life.
