Human dna polymerase alpha
WebAbstract. The primary sequence of human DNA polymerase {alpha} deduced from the full-length cDNA contains regions of striking similarity to sequences in replicative DNA polymerases from Escherichia coli phages PRD1 and T4, Bacillus phage {phi}19, yeast DNA polymerase I, yeast linear plasmid pGKL1, maize S1 mitochondrial DNA, herpes family … WebGene expression of human DNA polymerase alpha-DNA primase, a principal chromosomal replication enzyme complex, is up-regulated during the entrance of a cell from quiescence into the mitotic cell cycle. In contrast, expression of these genes is greatly reduced in fibroblasts rendered temporarily quiescent by contact inhibition or serum …
Human dna polymerase alpha
Did you know?
DNA polymerase alpha also known as Pol α is an enzyme complex found in eukaryotes that is involved in initiation of DNA replication. The DNA polymerase alpha complex consists of 4 subunits: POLA1, POLA2, PRIM1, and PRIM2. Pol α has limited processivity and lacks 3′ exonuclease activity for … See more DNA polymerase alpha, like DNA primase, contains iron-sulfur clusters, that are critical in electron transport that uses DNA itself to transfer electrons at very high speeds; this process is involved in detecting DNA … See more • DNA+polymerase+alpha at the U.S. National Library of Medicine Medical Subject Headings (MeSH) This article incorporates text from the United States National Library of Medicine, which is in the public domain.
