FusionProtFeatures for IRS2_MLH1 |
| Main function of each fusion partner protein. (from UniProt) |
| Hgene | Tgene |
| IRS2 | MLH1 |
| May mediate the control of various cellular processes byinsulin. | Heterodimerizes with PMS2 to form MutL alpha, acomponent of the post-replicative DNA mismatch repair system(MMR). DNA repair is initiated by MutS alpha (MSH2-MSH6) or MutSbeta (MSH2-MSH3) binding to a dsDNA mismatch, then MutL alpha isrecruited to the heteroduplex. Assembly of the MutL-MutS-heteroduplex ternary complex in presence of RFC and PCNA issufficient to activate endonuclease activity of PMS2. Itintroduces single-strand breaks near the mismatch and thusgenerates new entry points for the exonuclease EXO1 to degrade thestrand containing the mismatch. DNA methylation would preventcleavage and therefore assure that only the newly mutated DNAstrand is going to be corrected. MutL alpha (MLH1-PMS2) interactsphysically with the clamp loader subunits of DNA polymerase III,suggesting that it may play a role to recruit the DNA polymeraseIII to the site of the MMR. Also implicated in DNA damagesignaling, a process which induces cell cycle arrest and can leadto apoptosis in case of major DNA damages. Heterodimerizes withMLH3 to form MutL gamma which plays a role in meiosis.{ECO:0000269|PubMed:16873062, ECO:0000269|PubMed:18206974,ECO:0000269|PubMed:20020535, ECO:0000269|PubMed:21120944,ECO:0000269|PubMed:9311737}. |
| Retention analysis result of each fusion partner protein across 39 protein features of UniProt such as six molecule processing features, 13 region features, four site features, six amino acid modification features, two natural variation features, five experimental info features, and 3 secondary structure features. Here, because of limited space for viewing, we only show the protein feature retention information belong to the 13 regional features. All retention annotation result can be downloaded at . * Minus value of BPloci means that the break pointn is located before the CDS. |
