Relevance to Autism

Genetic association has been found between the PTGS2 gene and autism in a Korean population cohort (Yoo et al., 2008).

Molecular Function

The encoded protein is a key enzyme for prostaglandin synthesis. It has prostagl andin-endoperoxide synthase activity.

Model Summary

Mutants show increased ambulatory activity, increased repetitive digging, and increased anxiety. Changes in gene expression are also evident, especially in males.

Model Type: Genetic
Model Genotype: Homozygous
Mutation: Ptgs2^Y385F (also known as Ptgs^2tm1.1Fun) mice are a genetic mouse model for selective COX2 (i.e., PTGS2) inactivation, which was created by a targeted point mutation of the Ptgs2 gene, resulting in a Y385F amino acid substitution, which results in the complete inhibition of COX2 activity (Yu et al., 2006).
Allele Type: LOF Knockin
