FusionProtFeatures for POLD2_CHST14 |
| Main function of each fusion partner protein. (from UniProt) |
| Hgene | Tgene |
| POLD2 | CHST14 |
| As a component of the trimeric and tetrameric DNApolymerase delta complexes (Pol-delta3 and Pol-delta4,respectively), plays a role in high fidelity genome replication,including in lagging strand synthesis, and repair(PubMed:12403614, PubMed:16510448, PubMed:19074196,PubMed:20334433, PubMed:24035200). Pol-delta3 and Pol-delta4 arecharacterized by the absence or the presence of POLD4. Theyexhibit differences in catalytic activity. Most notably, Pol-delta3 shows higher proofreading activity than Pol-delta4(PubMed:19074196, PubMed:20334433). Although both Pol-delta3 andPol-delta4 process Okazaki fragments in vitro, Pol-delta3 may alsobe better suited to fulfill this task, exhibiting near-absence ofstrand displacement activity compared to Pol-delta4 and stallingon encounter with the 5'-blocking oligonucleotides. Pol-delta3idling process may avoid the formation of a gap, while maintaininga nick that can be readily ligated (PubMed:24035200). Along withDNA polymerase kappa, DNA polymerase delta carries outapproximately half of nucleotide excision repair (NER) synthesisfollowing UV irradiation (PubMed:20227374). Under conditions ofDNA replication stress, required for the repair of brokenreplication forks through break-induced replication (BIR)(PubMed:24310611). Involved in the translesion synthesis (TLS) oftemplates carrying O6-methylguanine or abasic sites performed byPol-delta4, independently of DNA polymerase zeta (REV3L) or eta(POLH). Facilitates abasic site bypass by DNA polymerase delta bypromoting extension from the nucleotide inserted opposite thelesion. Also involved in TLS as a component of the POLZ complex.Along with POLD3, dramatically increases the efficiency andprocessivity of DNA synthesis of the minimal DNA polymerase zetacomplex, consisting of only REV3L and REV7 (PubMed:24449906).{ECO:0000269|PubMed:12403614, ECO:0000269|PubMed:16510448,ECO:0000269|PubMed:19074196, ECO:0000269|PubMed:20227374,ECO:0000269|PubMed:20334433, ECO:0000269|PubMed:24035200,ECO:0000269|PubMed:24310611, ECO:0000269|PubMed:24449906}. | Catalyzes the transfer of sulfate to position 4 of theN-acetylgalactosamine (GalNAc) residue of dermatan sulfate. Playsa pivotal role in the formation of 4-0-sulfated IdoA blocks indermatan sulfate. Transfers sulfate to the C-4 hydroxyl ofbeta1,4-linked GalNAc that is substituted with an alpha-linkediduronic acid (IdoUA) at the C-3 hydroxyl. Transfers sulfate moreefficiently to GalNAc residues in -IdoUA-GalNAc-IdoUA- than in-GlcUA-GalNAc-GlcUA-sequences. Has preference for partiallydesulfated dermatan sulfate. Addition of sulfate to GalNAc mayoccur immediately after epimerization of GlcUA to IdoUA. Appearsto have an important role in the formation of the cerebellarneural network during postnatal brain development.{ECO:0000269|PubMed:19661164}. |
