ZNF238

C2H2-type zinc finger proteins, such as ZNF238, act on the molecular level as transcriptional activators or repressors and are involved in chromatin assembly.[supplied by OMIM

Full Name

zinc finger protein 238

Function

Transcriptional repressor that plays a role in various developmental processes such as myogenesis and brain development. Plays a key role in myogenesis by directly repressing the expression of ID2 and ID3, 2 inhibitors of skeletal myogenesis. Also involved in controlling cell division of progenitor cells and regulating the survival of postmitotic cortical neurons. Specifically binds the consensus DNA sequence 5'-[AC]ACATCTG[GT][AC]-3' which contains the E box core, and acts by recruiting chromatin remodeling multiprotein complexes. May also play a role in the organization of chromosomes in the nucleus.

Involvement in disease

Intellectual developmental disorder, autosomal dominant 22 (MRD22):
A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Additional MRD22 patients have limited or no speech, and variable but characteristic facial features, including round face, prominent forehead, flat nasal bridge, hypertelorism, epicanthal folds, and low-set ears. Other features may include hypotonia, poor growth, microcephaly, agenesis of the corpus callosum, and seizures.
