Area of Science:

  • Genomics
  • Molecular Biology
  • Developmental Biology

Background:

  • Human gene count is similar to simpler organisms, suggesting complexity arises from post-transcriptional regulation.
  • Alternative splicing is a major mechanism contributing to molecular complexity in higher eukaryotes.
  • Despite over half of human genes undergoing alternative splicing, its biological relevance and regulation remain poorly understood.

Purpose of the Study:

  • To highlight the utility of reverse genetics in studying regulated splicing.
  • To provide a guide for generating conditional knockout mouse models for splicing research.
  • To facilitate the study of alternative splicing in development and disease.

Main Methods:

  • Focus on the conditional knockout approach.
