Ctcfl | Transcriptional repressor CTCFL; Testis-specific DNA binding protein responsible for insulator function, nuclear architecture and transcriptional control, which probably acts by recruiting epigenetic chromatin modifiers. Plays a key role in gene imprinting in male germline, by participating in the establishment of differential methylation at the IGF2/H19 imprinted control region (ICR). Directly binds the unmethylated H19 ICR and recruits the PRMT7 methyltransferase, leading to methylate histone H4 'Arg-3' to form H4R3sme2. This probably leads to recruit de novo DNA methyltransferases a [...] (636 aa) | ||||
Pole | DNA polymerase epsilon catalytic subunit A; Catalytic component of the DNA polymerase epsilon complex (By similarity). Participates in chromosomal DNA replication. Required during synthesis of the leading DNA strands at the replication fork and binds at/or near replication origins and moves along DNA with the replication fork. Has 3'-5' proofreading exonuclease activity that corrects errors arising during DNA replication (By similarity). It is also involved in DNA synthesis during DNA repair (By similarity). Belongs to the DNA polymerase type-B family. (2283 aa) |
