Rpa1 | Replication protein A 70 kDa DNA-binding subunit; As part of the heterotrimeric replication protein A complex (RPA/RP-A), binds and stabilizes single-stranded DNA intermediates, that form during DNA replication or upon DNA stress. It prevents their reannealing and in parallel, recruits and activates different proteins and complexes involved in DNA metabolism. Thereby, it plays an essential role both in DNA replication and the cellular response to DNA damage. In the cellular response to DNA damage, the RPA complex controls DNA repair and DNA damage checkpoint activation. Through recruit [...] (644 aa) | ||||
Sult2b1 | Sulfotransferase 2B1; Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation. Preferentially sulfonates cholesterol. Catalyzes sulfation of the 3beta-hydroxyl groups of steroids, such as, pregnenolone and dehydroepiandrosterone (DHEA). Cholesterol sulfation is approximately 10-fold higher than for pregnenolone and 20-fold higher than for DHEA. Plays a role in epidermal cholesterol metabolism and in the regulation of epidermal proliferation and differentiation (By similarity). (338 aa) |
