| Type: | Domain | Name: | DNA methyltransferase 1-associated 1 |
| Description: | This entry represents a domain found in DNA methyltransferase 1-associated protein 1 (DMAP1). DNA methylation can contribute to transcriptional silencing through several transcriptionally repressive complexes, which include methyl-CpG binding domain proteins (MBDs) and histone deacetylases (HDACs). The chief enzyme that maintains mammalian DNA methylation, DNMT1, can also establish a repressive transcription complex. The non-catalytic N terminus of DNMT1 binds to HDAC2 and DMAP1, and can mediate transcriptional repression. DMAP1 has intrinsic transcription repressive activity, and binds to the transcriptional co-repressor TSG101. DMAP1 is targeted to replication foci through interaction with the far N terminus of DNMT1 throughout S phase, whereas HDAC2 joins DNMT1 and DMAP1 only during late S phase, providing a platform for how histones may become deacetylated in heterochromatin following replication []. | Short Name: | DMAP1 |
