Phosphatases and Diseases

Cancer

DUSP3 (VHR)

DUSP3 is a negative regulator of ERK and JNK pathways in in vitro studies in several cell lines. Though its role is involved in human cancer, its has contradictory roles since it has been alternatively described as having tumor suppressive and oncogenic properties [1].

DUSP26 (MKP8)

DUSP26 (aka MKP8) is a novel p53 phosphatase and inhibits p53 tumor suppressor functions in human neuroblastoma [2].

PPM1D (WIP1)

PPM1D as a frequent target of somatic mutation and as a potential therapeutic target in brainstem gliomas [3].

Other diseases

PTPRQ and deafness

See OMIM.

MTMR14 and centronuclear myopathy

See OMIM.
