POLI - DNA polymerase iota Gene

Homo sapiens

Also known as eta2; RAD30B; RAD3OB

Gene ID: 11201 | Gene type: protein coding

About POLI

Cytogenetic location: 18q21.2 Genomic coordinates (GRCh38): 18:54,269,479-54,321,266 (from NCBI)

This gene has 16 transcripts (splice variants), 184 orthologues and 5 paralogues. Ubiquitous expression in thyroid (RPKM 9.1), testis (RPKM 7.6) and 25 other tissues.

Summary

The protein encoded by this gene is an error-prone DNA Polymerase involved in DNA repair. The encoded protein promotes DNA synthesis across lesions in the template DNA, which other polymerases cannot do. The encoded polymerase inserts deoxynucleotides across lesions and then relies on DNA Polymerase zeta to extend the nascent DNA strand to bypass the lesion. [provided by RefSeq, May 2017]
