Summaries for MAP2K2 Gene

Entrez Gene Summary for MAP2K2 Gene

  • The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase is known to play a critical role in mitogen growth factor signal transduction. It phosphorylates and thus activates MAPK1/ERK2 and MAPK2/ERK3. The activation of this kinase itself is dependent on the Ser/Thr phosphorylation by MAP kinase kinase kinases. Mutations in this gene cause cardiofaciocutaneous syndrome (CFC syndrome), a disease characterized by heart defects, mental retardation, and distinctive facial features similar to those found in Noonan syndrome. The inhibition or degradation of this kinase is also found to be involved in the pathogenesis of Yersinia and anthrax. A pseudogene, which is located on chromosome 7, has been identified for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for MAP2K2 Gene

MAP2K2 (Mitogen-Activated Protein Kinase Kinase 2) is a Protein Coding gene. Diseases associated with MAP2K2 include cardiofaciocutaneous syndrome 4 and map2k2-related cardiofaciocutaneous syndrome. Among its related pathways are PI3K-Akt signaling pathway and PI-3K cascade. GO annotations related to this gene include protein serine/threonine kinase activity and PDZ domain binding. An important paralog of this gene is MAP2K7.

Heart defects include pulmonic stenosis, atrial septal defects and hypertrophic cardiomyopathy. Some affected individuals present with ectodermal abnormalities such as sparse, friable hair, hyperkeratotic skin lesions and a generalized ichthyosis-like condition. Typical facial features are similar to Noonan syndrome. They include high forehead with bitemporal constriction, hypoplastic supraorbital ridges, downslanting palpebral fissures, a depressed nasal bridge, and posteriorly angulated ears with prominent helices. {ECO:0000269 PubMed:16439621, ECO:0000269 PubMed:18042262, ECO:0000269 PubMed:20358587}.
