Protein

DNA polymerase epsilon subunit 3

Gene

POLE3

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Forms a complex with DNA polymerase epsilon subunit CHRAC1 and binds naked DNA, which is then incorporated into chromatin, aided by the nucleosome-remodeling activity of ISWI/SNF2H and ACF1.

Catalytic activityi

Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).

Interactioni

Subunit structurei

Component of the epsilon DNA polymerase complex consisting of four subunits: POLE, POLE2, POLE3 and POLE4. Interaction with POLE4 is a prerequisite for further binding with POLE and POLE2. Interacts with CHRAC1. Together with CHRAC1, ACF1 and ISWI/SNF2H proteins, it forms the ISWI chromatin-remodeling complex, CHRAC.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
