NTH

Protein FULL name:

endonuclease III-like protein 1 [Homo sapiens].


NTH (Homo sapiens) is product of expression of NTHL1 gene.


NTH is involved in:

BER in Homo sapiens

Keywords:



FUNCTION: Has both an apurinic and/or apyrimidinic endonuclease activity and a DNA N-glycosylase activity. Incises damaged DNA at cytosines, thymines and guanines. Acts on a damaged strand, 5' from the damaged site. Required for the repair of both oxidative DNA damage and spontaneous mutagenic lesions.

CATALYTIC ACTIVITY: The C-O-P bond 3' to the apurinic or apyrimidinic site in DNA is broken by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate.

COFACTOR: Binds 1 4Fe-4S cluster. The cluster is not important for the catalytic activity, but which is probably involved in the proper positioning of the enzyme along the DNA strand.

INTERACTION: O14556:GAPDHS; NbExp=1; IntAct=EBI-1049350, EBI-1057431; P12883:MYH7; NbExp=1; IntAct=EBI-1049350, EBI-519141; P36639:NUDT1; NbExp=1; IntAct=EBI-1049350, EBI-1048967; Q9HC36:RNMTL1; NbExp=1; IntAct=EBI-1049350, EBI-1045440;

SUBCELLULAR LOCATION: Nucleus.

TISSUE SPECIFICITY: Widely expressed with highest levels in heart and lowest levels in lung and liver.

DEVELOPMENTAL STAGE: Expression levels are regulated during the cell cycle with increased levels during early and mid S-phase.

SIMILARITY: Belongs to the nth/mutY family.

CAUTION: It is uncertain whether Met-1, Met-9 or Met-16 is the initiator.

SEQUENCE CAUTION: Sequence=AAC51136.1; Type=Erroneous initiation; Sequence=AAH03014.1; Type=Erroneous initiation; Sequence=BAA19413.1; Type=Erroneous initiation; Sequence=BAA32695.1; Type=Erroneous initiation;
