Point Mutation Knockin Rat Models
A point mutation Knockin rat defines an animal model in which one or more nucleotides are constitutively mutated.
Gain or loss of function: The insertion, deletion, nonsense and sense mutations can alter the amino acid sequence of a given protein, and so dramatically affect its function.
Typical applications for point mutation Knockin rat models
For academic research:
For bio-pharmaceutical research & development:
Strengths and limitations of point mutation Knockin rat models
- Best way to reproduce human disease when due to mutations
- High physiological relevancy of the scientific data obtained from the model (regulatory elements conserved, under control of endogenous promoter, expression of all splice variants, etc.) = cleaner way than classical KO where the whole gene is deleted
- Phenotype due only to the mutation: alteration of a single function without disturbing other domains of a protein
- Mutation of the gene of interest may affect development, resulting in an impaired phenotype or embryonic death
→ Limitation can be bypassed by applying conditions such as time-specific gene inactivation
- 1. Modification or disruption of splicing regulation
2. Genetic redundancy
→ Can be assessed via constitutive Knockout of the gene of interest
