Relevance to Autism

Mice with a conditional knockout of MAPK1 in the CNS exhibit marked anomalies in multiple aspects of social behaviors, decreased anxiety-related behaviors and impaired long-term memory (Satoh et al., 2011).

Molecular Function

Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway.
