| CXorf23 | POLA1 |
| Lectin that binds to various sugars: galactose > mannose= fucose > N-acetylglucosamine > N-acetylgalactosamine(PubMed:10224141). Acts as a chemoattractant, probably involved inthe regulation of cell migration (PubMed:28301481).{ECO:0000269|PubMed:10224141, ECO:0000269|PubMed:28301481}. | Plays an essential role in the initiation of DNAreplication. During the S phase of the cell cycle, the DNApolymerase alpha complex (composed of a catalytic subunitPOLA1/p180, a regulatory subunit POLA2/p70 and two primasesubunits PRIM1/p49 and PRIM2/p58) is recruited to DNA at thereplicative forks via direct interactions with MCM10 and WDHD1.The primase subunit of the polymerase alpha complex initiates DNAsynthesis by oligomerising short RNA primers on both leading andlagging strands. These primers are initially extended by thepolymerase alpha catalytic subunit and subsequently transferred topolymerase delta and polymerase epsilon for processive synthesison the lagging and leading strand, respectively. The reason thistransfer occurs is because the polymerase alpha has limitedprocessivity and lacks intrinsic 3' exonuclease activity forproofreading error, and therefore is not well suited forreplicating long complexes. In the cytosol, responsible for asubstantial proportion of the physiological concentration ofcytosolic RNA:DNA hybrids, which are necessary to preventspontaneous activation of type I interferon responses(PubMed:27019227). {ECO:0000269|PubMed:27019227,ECO:0000269|PubMed:9518481}. |
| 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. |
