Rea1

Rea1 is a protein found in yeast. It plays a critical role in DNA replication, specifically in the process of unwinding DNA. Rea1 is part of a complex that acts as a helicase, an enzyme that separates the two strands of DNA. This unwinding is essential for DNA to be copied accurately during cell division. The Rea1 helicase is known to be involved in the replication of both nuclear and mitochondrial DNA in yeast. Its function is vital for maintaining the integrity of the genome. Mutations in the Rea1 gene can lead to significant problems with DNA replication, causing cells to grow slowly or die. Research into Rea1 helps scientists understand the fundamental mechanisms of DNA replication in eukaryotes, which are the type of cells found in organisms like yeast, plants, and animals. Understanding Rea1's precise role can provide insights into how DNA replication is regulated and how errors are prevented.
