BRCA2 | Breast cancer type 2 susceptibility protein; Involved in double-strand break repair and/or homologous recombination. Binds RAD51 and potentiates recombinational DNA repair by promoting assembly of RAD51 onto single-stranded DNA (ssDNA). Acts by targeting RAD51 to ssDNA over double-stranded DNA, enabling RAD51 to displace replication protein-A (RPA) from ssDNA and stabilizing RAD51- ssDNA filaments by blocking ATP hydrolysis. Part of a PALB2-scaffolded HR complex containing RAD51C and which is thought to play a role in DNA repair by HR. May participate in S phase checkpoint activation. [...] (3418 aa) | ||||
METTL4 | N(6)-adenine-specific DNA methyltransferase METTL4; N(6)-adenine-specific DNA methyltransferase that mediates methylation of DNA on the 6th position of adenine (N(6)- methyladenosine) and is required to regulate Polycomb silencing. N(6)- methyladenosine deposition by METTL4 triggers ubiquitination and degradation of sensor proteins ASXL1 and MPND, leading to inactivation of the PR-DUB complex and subsequent preservation of Polycomb silencing; Belongs to the MT-A70-like family.
