EXO1

exonuclease 1

On chromosome: 1q42-q43
Known also as: HEX1; hExoI;


NCBI Gene ID: 9156
NCBI Ensembl Id: ENSG00000174371
MIM Id: (from NCBI OMIM database) 606063
Species: Homo sapiens

This gene encodes a protein with 5' to 3' exonuclease activity as well as an RNase H activity. It is similar to the Saccharomyces cerevisiae protein Exo1 which interacts with Msh2 and which is involved in mismatch repair and recombination. Alternative splicing of this gene results in three transcript variants encoding two different isoforms. [provided by RefSeq]
