Mitogen-activated protein kinase kinase 2 (MAP2K2) is a gene that encodes a protein that is a member of the MAP kinase kinase family. The protein functions as a dual specificity protein kinase that regulates mitogen growth factor signal transduction by phosphorylating and activating MAPK1/ERK2 and MAPK2/ERK3. Missense and silent mutations are observed in cancers such as bone cancer, skin cancer, and stomach cancer.

MAP2K2 is altered in 0.66% of all cancers with colon adenocarcinoma, lung adenocarcinoma, cutaneous melanoma, breast invasive ductal carcinoma, and melanoma having the greatest prevalence of alterations [3].

The most common alterations in MAP2K2 are MAP2K2 Mutation (0.50%), MAP2K2 Loss (0.05%), MAP2K2 Amplification (0.04%), MAP2K2 R231C (0.02%), and MAP2K2 V262I (0.01%) [3].
